We'll definitely take that error to finish off this year's race! Greipel's average speed is given below.
Stage 21: 11.54 m/s (41.56 kph or 25.82 mph)
The big prize, of course, goes to Chris Froome who makes it three out of four. Froome is now in the upper echelon of Tour de France cyclists. I was wrong to pick against the defending champion! Froome's average speed is given below.
Chris Froome: 11.00 m/s (39.60 kph or 24.61 mph)
Not bad for 3528.5 km (2192.5 mi)! Congratulations to Froome and all the cyclists for a great Tour de France. I wish I could have seen more of the race, but my family will soon be moving across the pond. And we've got packing to do!
Jon Izagirre of Spain won this year's final mountain stage. Spain can celebrate its first Tour de France stage win this year! Izagirre's winning time and a comparison with our prediction is given below.
I'll take that error on such an arduous mountain stage. Bardet's average speed is given below.
Stage 19: 9.575 m/s (34.47 kph or 21.42 mph)
Froome still has the yellow jersey, and he widened his lead over second place. Nairo Quintana could only cut ten seconds off of Froome's lead over him. Tomorrow is the last shot climbers will have to take down Froome, but his lead looks mighty impressive for the final mountain stage. A category-2 climb, two category-1 climbs, and an HC climb will have cyclists excited about the big downhill finish. Our prediction is given below.
Stage 20: 4h 01' 44" (prediction)
Will Froome hold the yellow jersey? Hard to imagine losing it the way he's cycled this year.
Chris Froome showed why he's a multiple Tour de France champion today. He dominated the mountain time trial and makes me wonder if the Tour de France is over. His winning time and a comparison with our prediction appear below.
I was hoping the winner would come in under half an hour, but Froome was impressive nonetheless. His average speed is below.
Stage 18: 9.224 m/s (33.21 kph or 20.63 mph)
Froome won the first mountain stage and he dominated the mountain time trial. I picked Nairo Quintana in my TOUR magazine interview. Froome has a 04' 37" on Qunitana, and a nearly four-minute lead on second place. There are two more mountain stages to go. Time is running out! Our prediction for Stage 19 is below.
Stage 19: 4h 04' 57" (prediction)
Besides an HC-climb in the middle, a category-1 climb finishes the stage. Another uphill finish!
Russian Ilnur Zakarin won today's arduous mountain stage with a time nearly a minute faster than anyone else. This is Zakarin's first Tour de France stage win. Below is Zakarin's winning time and a comparison with our prediction.
What's funny for me watching a stage is that I don't root for our prediction unless at the end I think we are really close. I wanted to see the elite tackle today's mountains and come in under five hours. And did they ever! Check out Zakarin's average speed below.
Stage 17: 11.12 m/s (40.03 kph or 24.87 mph)
That speed is 2 kph faster than what race organisers had as their upper limit on the time schedule. Incredible to average 40 kph today! We aren't happy to be more than 8% off today, but we'll have plenty to study when the race is over. Several determined cyclists clearly outputted more power today than we had in our model. We'll have a clearer picture of elite cyclist power output after this Tour de France is over. Tomorrow's Stage 18 is a 17-km (11-mi) mountain individual time trial. Cyclists will be back in France for the uphill time trial. They'll get a chance to sprint on the downhill finish, though. Our prediction is given below.
Stage 18: 29' 27" (prediction)
I definitely want to see cyclists coming in under half an hour tomorrow.
I'm busily getting items packed for our big move across the pond next week. It hit me this afternoon that I'd not put our Stage 17 prediction online. Well here it is:
Stage 17: 5h 00' 10" (prediction)
Cyclists will compete in the Swiss Alps tomorrow. A great category-1 climb to the 1527-m (5010-ft) peak at Col de la Forclaz will tire cyclists. But they'll have to rejuvenate on the descent because the HC-climb to Finhaut-Emosson at elevation 1960 m (6430 ft) will challenge even the most elite cyclist.
Peter Sagan has really discarded the bridesmaid label in this year's Tour de France! I can recall so many stages in past years when he just missed out on winning a stage. Below is Sagan's winning time and a comparison with our prediction.
We're not happy with that error! I don't see any indication of tailwinds or anything similar that would make cycling fast today. As I wondered at the end of yesterday's post, sprinters must have been going all out today. Check out Sagan's average speed below.
Stage 16: 13.09 m/s (47.14 kph or 29.29 mph)
That is incredibly fast, especially for a 209-km (130-mi) long stage. Even race organisers didn't think the average speed would be above 44 kph. To match Sagan's time (and the time of several other cyclists), our model cyclist would have needed nearly 21% more power output. We've done really well on a few stages this year, and we've had weather and teams' strategies thwart us on a couple of other stages. But we will have to take a closer look at today's stage. Tour de France cyclists certainly impress us!
Tomorrow is the second and final rest day. Cyclists will hang out in Berne, Switzerland. Chris Froome still dons the yellow jersey. This year's race will surely be decided in the Alps. Get some rest tomorrow, cyclists. You're going to need it!
I'll be using this space as a sabbatical journal for another fortnight or so. Nothing comes to a close faster than a fruitful, yearlong sabbatical in England! But I've made the most of my time here, professionally and personally. I've written a good bit about various trips my family has taken, but I've not written as much about my research. There is a good reason for that. I was waiting to publish and present significant pieces of research. More research is set to be published, but I'll describe below some of the work that's kept me busy this past year. My time in the Netherlands last week will be the perfect vehicle for that description.
I attended the 11th Conference of the International Sports Engineering Association in Delft (click here for the conference webpage). I had never been to the Netherlands before. It was fantastic! I am both thoroughly impressed and incredibly jealous of the biking culture there. Wide bike lanes sit adjacent to car lanes. It was so easy getting around. The neighbourhood where I live in Virginia doesn't even have sidewalks. And biking is done at nontrivial risk because of speeding cars, a small fraction of which have drivers quite hostile to cyclists. If my hometown had a biking setup like what I saw in Delft, I could easily see myself biking to work on a regular basis. But riding on a 45-mph (72-kph) road, with some cars going well in excess of that speed limit, and no cycling lane make such an effort very unappealing. Hopping back in my car when I return isn't exactly something I'm looking forward to. But cycling in beautiful Delft was a lot of fun. The photo below shows me on my rented bike in front of the conference centre (click on the image for a larger view).
I relish going to a research conference. Meeting up with colleagues I've not seen in a year or more is just as great as meeting a slew of new people. Besides four great keynote addresses, I attended 37 talks and gave two talks. I couldn't see any more than that! There were three parallel sessions, meaning lots of talks that interested me had to be missed. As great as the talks were, the hallway discussions were even better. Enthusiasm was contagious and it was easy getting excited about the smallest detail in another's work. The organisers at Delft did a terrific job. We enjoyed great food for lunches and snacks, and the final conference dinner was a blast. I also loved getting to know people over beer and Dutch food in one of couple of lovely squares in town. All of us had the common feeling of love for our work and passion to learn more. I definitely left the conference with new ideas and novel ways to think about current research problems in my head.
My research efforts contributed three papers to the conference. I like that conference papers weren't simply dumped without review into a "conference proceedings" book. Papers for the Delft conference, like many other serious research conferences, were peer reviewed and allowed revision. One of my papers benefited from a reviewer's insight. Another reviewer gave good advice for the oral presentation I gave. Peer review is an indispensable step in the advancement of good science.
Chad Hobson, my talented undergraduate physics student from Lynchburg College, joined me in Delft for the conference. It is important to me that my research students publish and present their work. Not all my students are able to achieve a publication, but that's a goal I've had since I began at Lynchburg College in 2002. Chad presented our latest Tour de France work. He is lead author on our paper (click here for that paper) and deservedly so. His contributions to the work have advanced our Tour de France modelling in significant and critical ways. Chad is in the middle of his talk in the photo below (click on the image for a larger view).
I've collaborated with colleagues at the University of Tsukuba on studies involving the aerodynamics of non-spinning soccer balls. Previous work we published together showed why Brazuca was a better World Cup soccer ball than Jabulani. I presented our current work that combined wind-tunnel experiments with trajectory analysis. The latter approach is my speciality. The photo below shows me in the midst of my soccer talk (click on the image for a larger view).
And, no, I'm not doing a Jedi mind trick! The slide shows wind-tunnel force measurements, plotted in such a way as to illustrate stability, or lack thereof, in the five balls tested. Click here for our paper. We are getting a better understanding of knuckling effects.
My second presentation concerned part of the research I've done with my University of Sheffield colleagues. We have investigated friction between various types of tennis shoe tread and a hard-court playing surface. Sliding on hard courts isn't as prevalent as it is on clay courts, but it's becoming more popular. I showed some of our treads in the slide below (click on the image for a larger view).
There are so many options for studying tread shapes and courts interacting with each other. This research can certainly go on for years! Our first paper on this topic is here. We hope to have another one out soon.
Conference revelry was damped by the late-night news on Bastille Day that scores of people were killed in Nice. And that news is on top of the seemingly continuous streams of bad news from my home country. As I talked to people in Delft last week, I got such a strong sense of their hope and anticipation for future work. I'm sure I exuded those desires as well. Now think of all those killed in Nice and elsewhere. Innocent people with hope and anticipation for their futures. Gone. Families ruined forever. And for what purpose? Making sense of the senseless is nearly impossible. Maybe there will come a day when humans stop killing each other, but that day is a long, long way off.
Wind was not the factor today that it was yesterday, and our model got us near 1%. We'll take it! Below is Pantano's average speed.
Stage 15: 10.07 m/s (36.25 kph or 22.53 mph)
Tomorrow's stage finishes in Switzerland. Our prediction is given below.
Stage 16: 4h 46' 38" (prediction)
The day after tomorrow's stage is a rest day. Will cyclists increase their rest by holding back tomorrow in preparation for the Alps? Or will they go for it, thinking the rest day will be all that's required before the big mountain stages? We shall see!
Mark Cavendish won his fourth stage of this year's Tour de France. He won a stage in which riders fought massive headwinds all day. One report I saw had the head wind nearing 40 kph (25 mph). The wind killed our prediction, as seen below.
I know why we were so off, but I still hate to see so large an error. We had that same error on Stage 3. That stage reinforced the idea that we can be off if team strategies' are such as to hold cyclists back. Today's stage is a reminder that not knowing the weather can lead to a bad prediction. Check out Cavendish's average speed below.
Stage 14: 10.11 m/s (36.39 kph or 22.61 mph)
That is incredibly slow for a flat stage, even a long one. The slowest average speed the Tour de France time schedule makers considered was 40 kph (25 mph). To match the time for today's stage, we would have needed to include a 10.7 kph (6.67 mph) headwind on our model cyclist -- for the entire 208.5 km (129.6 mi). We didn't miss today's stage because of poorly implemented physics. We missed it because we had no idea ahead of time that riders would face headwinds. But that's part of the unknown associated with the modelling the Tour de France.
Tomorrow's Stage 15 contains two category-1 climbs and a big HC climb. The stage features a fast descent to the finish. Below is our prediction.
Stage 15: 4h 22' 06" (prediction)
I like our prediction -- as long as Mother Nature doesn't get in the way!
Tom Dumoulin of the Netherlands easily won today's individual time trial. How appropriate that the same cyclist who won the stage when I arrived in the Netherlands last Sunday wins the stage on the day I left the Netherlands. A great bookend for a wonderful time spent in Delft. I'll write more about the conference in a few days, but for now, check out Dumoulin's winning time.
Stage 12 was cut short by 6.5 km because of incredibly fast winds at the summit of Mont Ventoux. Thomas De Gent of Belgium won today's truncated stage. His winning time and a comparison with our pediction are given below.
I confess that I am stunned by that average speed. Cyclists were fast today! I can't imagine that average speed for myself. Tour de France cyclists are the best of the best for sure. Did they know ahead of time that tomorrow's massive climb to Mount Ventoux was going to be cut short because of massive winds at the summit? They had to know they'd not need to save as much energy for tomorrow.
We learned that the final 6.5 km of tomorrow's last climb will be cut from the stage. Below is our original prediction, our original prediction for the final 22 km, and our prediction based on removing the final 6.5 km.
Stage 12: 4h 55' 23" (prediction)
Stage 12: 58' 54" (prediction for final 22 km)
Stage 12: 4h 37' 31" (prediction with final 6.5 km missing)
If the race committee does exclude the final 6.5 km, we'll go with the last time on the above list as our prediction. It's too bad the final climb has to be cut short. We've been waiting on that climb since it was released.
I enjoyed a great first day of research talks here in Delft, the Netherlands. The conference is off to a good start! But being tied up all day in a conference means I couldn't see any of the Tour de France. I'm back in my hotel room for a few minutes before heading out to dinner. Below is Michael Matthews' winning time and a comparison with our prediction.
My student, Chad Hobson, and I are having a great time in Delft, the Netherlands. I saw old friends today that I'd not seen in several years. We also met several new people and toured the labs at Delft. Nothing like being around people excited about research!
Below is our Stage 10 prediction.
Stage 10: 4h 32' 45" (prediction)
Read about tomorrow's medium mountain stage online. I'm having too much fun in Delft and need to get back on my bicycle and explore the city!
I've been travelling all day and I missed yet another Tour de France stage. Nothing like being in Europe and not watching the best bike race on the planet! Below is Tom Dumoulin's winning time and a comparison with our prediction.
From what I read, there were thunderstorms at the finish. Did that slow riders down and lead to the above discrepancy? Please e-mail me and let me know! I love it that Dumoulin is from the Netherlands, and I'm in the Netherlands right now! I'm here for an international research conference. My student, Chad Hobson, is here, too. We are checking out the Euro 2016 final while I'm writing this blog post. Portugal just won it!
Below is Dumoulin's average speed.
Stage 9: 9.719 m/s (34.99 kph or 21.74 mph)
Tomorrow is the Tour de France's first rest day. I'll get our Stage 10 prediction up before tomorrow comes to a close here in the Netherlands. Until then, we'll be happy with our prediction today.
Oh how I wish I could have seen today's stage! We have friends visiting from the US and we showed them Sheffield for the entire day, from a traditional tea to a pub visit to time in the park. But I missed Stage 8 as Chris Froome dominated the competition to take the yellow jersey. Below is Froome's wining time compared to our prediction.
Now that's an error we can tolerate! We are back under 2.5%, which is great. Froome's average speed is given below.
Stage 8: 10.31 m/s (37.10 kph or 23.05 mph)
That's impressive! Even though we predicted a slightly better time, Froome still completed the stage in a time that amazes me. Well done!
From Spain to Andorra, tomorrow's Stage 9 is a 184.5-km (114.6-mi) mountain stage that will have riders battling in the Pyrenees. Three category-1 climbs, including at the start, will have riders tired by the time they get to the HC climb to finish the stage at the ski resort of Andorre Arcalis where the elevation is 2240 m (7349 ft). Our prediction is given below.
Stage 9: 5h 02' 33" (prediction)
I fully admit that we are predicting a fast time. Come on, climbers, challenge Froome tomorrow!
We're not happy with that error! Check out Cummings' average speed below.
Stage 7: 11.68 m/s (42.03 kph or 26.12 mph)
That's at the top of the time schedule range; our prediction was closer to the bottom of that range. Cyclists enjoyed a bit of a tailwind, but temperatures were comparable to yesterday's stage. The competition to reach the summit of Col d' Aspin was fierce and the downhill sprint that followed the climb was incredibly fast. Kudos to the cyclists for dazzling us once again! Tomorrow's 184-km (114-mi) Stage 8 is this year's first mountain stage. Beginning in Pau, cyclists will head southeast through the Pyrenees to Bagnères-de-Luchon. A massive HC-climb to the 2115-m (6939-ft) summit of Col du Tourmalet highlights the beginning of the stage. As if that weren't enough, cyclists will tackle a category-2 climb and two category-1 climbs before a fast downhill sprint to the finish. Below is our prediction.
Stage 8: 4h 50' 14" (prediction)
That prediction amounts to a fast day of racing. We want to see racing tomorrow like we saw today!
Mark Cavendish picked up his third stage win in this year's Tour de France. Cycling was a bit slow today. The peloton took it easy at times and cyclists seemed to be affected by the heat. Temperatures got to about 30 C (86 F), which is hot enough to be bothered when one's cycling competitively for nearly five hours. Below is Cavendish's winning time and a comparison with our prediction.
We were a bit fast today, though I think the heat played a role in slowing cyclists down a little. Below is Cavendish's average speed.
Stage 6: 11.19 m/s (40.27 kph or 25.03 mph)
Had we know about the heat, we might have pulled the power down a little. But our model has done really well on four of the six stages so far, although we messed up one of those four when we cut the power too much. We were under 8% today, which was something we thought of as good a decade ago. Now we want to do better!
Stage 7 is 162.5-km (101.0-mi) long medium-mountain stage that begins in the commune of L'Isle-Jourdain. A category-1 climb to the 1490-m (4888-ft) summit of Col d'Aspin near the end of the stage will introduce the riders to the French Pyrenees. I can't wait to see that climb! After the summit will be a downhill sprint to Lac de Payolle. Our prediction is below.
Stage 7: 4h 11' 35" (prediction)
Did cyclists save some energy today for tomorrow's big climb? If so, we could be a little slow. But we'll see how the model performs tomorrow.
After yesterday's disastrous decision to drop cyclist power output by 20%, and thus missing the chance to have publicly predicted Stage 4 to 0.24%, we put our trust in our model for today's Stage 5. It sure paid off! Belgium's Greg Van Avermaet got his second career individual stage win in the Tour de France, and he wrested the yellow jersey from Peter Sagan. Below is Avi's winning time and a comparison with our prediction.
It's great being back under 1%! Below is Avi's average speed.
Stage 5: 10.86 m/s (39.08 kph or 24.29 mph)
Given the climbs in today's stage, that's an impressive average speed. Tomorrow's Stage 6 is a 190.5-km (118.4-mi) flat stage with an impressive downhill just 23.5 km (14.6 mi) into the stage. Beginning in the commune of Arpajon-sur-Cère, cyclists will head southwest to Montauban. The Pyrenees are getting closer! Below is our prediction.
Stage 6: 4h 21' 26" (prediction)
We're sticking with our model -- no power tweaking. I'll be anxious to see if we've figured out Stage 6.
Yesterday's stage and today's stage provided us with a real learning experience, and a humbling one at that. Last year was the first time we made adjustments to our model while the Tour de France was taking place. We tried to make tweaks based on strategies we thought were in play. For the most part, our adjustments worked extremely well.
Now to today's learning experience. Marcel Kittel won today's stage 4 with the time given below.
After yesterday's enigmatic slow stage, we thought cyclists were holding back, saving energy for later stages. Given that today's stage was longer than yesterday's stage, we thought power outputs would be reduced again. As I noted yesterday, we would have needed to cut power by a third to hit yesterday's time. We decided to cut power by 20% today, thinking we'd see another slow stage. We should not have done that! I cringed when I saw that had we not altered our model by reducing the power, we would have missed today's stage by just 47". Getting spooked by yesterday's stage caused us to think that teams' strategies were such that we had too much power for the long, flat stages. We should have seen yesterday as an anomaly and trusted our model for today's stage. But we can't go back in time and claim a great prediction today. Our model performed great; we misread the cyclists' strategies. Part of good science is being as honest as possible.
Below is Kittel's average speed.
Stage 4: 12.05 m/s (43.38 kph or 26.95 mph)
We are going to trust our model for tomorrow's Stage 5, which is a 216-km (134-mi) medium-mountain stage that starts in Limoges, where Stage 4 ended. Cyclists will head southeast to the mountain resort of Le Lioran. Two category-2 climbs near the end of the stage should make for great racing. Our prediction is given below.
Stage 5: 5h 29' 33" (prediction)
We'll stick with our original prediction and hope racing tomorrow is more like today than yesterday.
Today's Stage 3 was as bizarre a Tour de France stage as I've ever seen. It was SO SLOW! The peloton looked like molasses moving down the road. After nearly six hours, Mark Cavendish crossed the finish line. Below is his winning time and a comparison with our prediction.
I need to check my archives, but that might be the worst prediction we've ever made! Check out Cavendish's average speed below.
Stage 3: 10.35 m/s (37.26 kph or 23.15 mph)
Keep in mind that today's stage was a flat stage. The above average speed is comparable to what we've seen on a few mountain stages. It's also nearly 2 kph less than the slowest time schedule average speed given by Tour de France organisers. No wonder race commentators were using phrases like "slow motion" and "snail's pace"! As happy as we were to be under 1% yesterday, we're just as mystified to be nearly 15% off today. I tell audiences during my Tour de France talks that there are many things we cannot know about the race, and teams' strategies are right at the top of the list. The same model that nailed yesterday's stage needed its cyclist power output cut by nearly a third today. Riders were clearly holding back, and I don't claim that because we had such a bad prediction. Learning as the race unfolds is a lot of fun, and we certainly learned something today. Tomorrow's Stage 4 is a 237.5-km (147.6-mi) flat stage, which is this year's longest stage. Were cyclists saving energy today for tomorrow's long ride? That could very well have been the teams' strategies. Beginning in the commune of Saumur, the stage takes riders southeast to Limoges. Below is our prediction.
Stage 4: 5h 56' 59" (prediction)
The above would have been a great pick for today! Tomorrow's stage is 14 km (8.7 mi) longer than today's stage. I hope the peloton moves a little faster tomorrow.
I always think of Peter Sagan as coming in second. There are so many stages of the Tour de France that I remember Sagan just coming up short. That wasn't the case today as The Terminator took Stage 2. Below is Sagan's winning time and a comparison with our prediction.
We're always excited to be under 1%! Sagan's average speed is given below.
Stage 2: 11.69 m/s (42.09 kph or 26.16 mph)
Sagan now has the yellow and green jerseys. Mark Cavendish sits in 75th place out of 198 riders. Tomorrow's Stage 3 is 223.5 km (138.9 mi) long and classified as flat. Beginning on the coast at Granville, the stage takes riders south to the city of Angers. Our prediction is given below.
Stage 3: 5h 07' 03" (prediction)
Our prediction is a bit of a challenge to the cyclists. We want to see a rider finish the stage close to five hours. That's a long time in the saddle!
We'll definitely take that error on the first stage! Here is Cavendish's average speed:
Stage 1: 12.33 m/s (44.39 kph or 27.59 mph)
Cavendish will don the yellow jersey for tomorrow's 183-km (114-mi) Stage 2. The hilly stage begins in the commune of Saint-Lô, moves south, then southwest, before turning north along the coast toward the commune of Cherbourg-en-Cotentin. Our prediction is given below.
Stage 2: 4h 22' 59" (prediction)
There are three category 4 climbs early on and a category 3 climb to finish the stage. Will Cavendish be able to enjoy his first yellow jersey for more than a day?
The 103rd Tour de France commences tomorrow. For those of us that follow the yearly race, a day like today makes us say, "Finally!" I thoroughly enjoyed giving my talk this afternoon on my Tour de France and World Cup football research work. I tried to whet the appetite of those in the audience anticipating the start of tomorrow's first stage. My colleague, Zing, snapped the photo below just before my talk got underway (click on the image for a larger view).
I unveiled our Stage 1 prediction during the talk, but before I do that in this space, a few more words. In past years, I've watched the Tour de France in my Lynchburg College office via an internet feed. I could snag a few images of each stage by simply printing my computer screen to a file. Stages would usually end around noon, meaning I could watch in the morning and still work a mostly full day afterwards. Now that I'm in England, stages will be run during afternoons, finishing in early evenings. That makes it much harder for me to follow the race and still get lots of work done. So despite being much closer to the action this year, my blog posts will be less detailed and contain fewer images. I'll still post a prediction before each stage is run, though.
Tomorrow's Stage 1 begins in the French commune of Mont Saint-Michael. Cyclists will head mostly north along the coast for the 188-km (117-mi) flat stage, which ends on Utah Beach in Sainte-Marie-du-Mont. Below is our prediction.
Stage 1: 4h 20' 25" (prediction)
Will we be fast? Slow? Nail it? Who knows? But it'll be fun seeing how close we come!
I don't know! That response happens to be one of the best responses a scientist, or anyone for that matter, can give to a question. No reason to assert a claim without data and evidence to support the claim. As a scientist, I'm trained to make conclusions based on data and evidence. But I've had a lot of fun in recent years publishing Tour de France stage-winning-time predictions on this blog. My research students and I have honed a physical model for a dozen years now. The recipe is fairly simple. We take stage profile data, add some cyclist power output, toss in some air resistance and road friction, and then mix the ingredients up with the laws of physics. A tasty summer treat indeed! But the question that serves as this post's title is one I'm asked by media every year. It's a fun question because I can't possibly know what will happen over the course of a gruelling three-week-long race. Will there be big crashes? Injuries? Which stages will be hit with bad weather? Cycling teams certainly aren't sharing their strategies with me. I do freely admit, though, that publishing our winning stage-time predictions prior to each stage being run has made the science much more exciting -- and the science was already exciting! For the first time, I made a prediction for the overall winner. I did so with all the caveats mentioned in the previous paragraph. Will I feel bad if my pick doesn't win? As long as he competes well and doesn't get injured, no, I won't feel bad. There are a handful of elite riders with strong teams who have legitimate shots at winning cycling's most famous race. I picked one of them -- but I'm not revealing the name in this space. At least not yet. I was recently interviewed by TOUR Magazine, which is based in Germany. My prediction for the overall winner sits on page 36 of the current issue (July 2016). Because the magazine was gracious enough to chat with me about my Tour de France research work, I'll throw the magazine a little love and ask that if you're really interested in my pick, you'll go there. The 103rd Tour de France begins day after tomorrow (Saturday, 2 July). I've been invited by the Department of Mechanical Engineering here at the University of Sheffield to give a talk on my Tour de France and World Cup football research. My talk will begin at 2 pm on Friday, 1 July and will be held in LT 15 in the Sir Frederick Mappin Building. I plan to unveil our Stage 1 prediction during the talk. I'll also post our prediction after the talk in this space. If asked during Q&A, I may even offer my pick for this year's winner!
I gave an invited talk today at the University of Sheffield. The topic is important to me, but the topic had never been the subject of one my talks before. I was asked to talk about writing a good journal article. Sure it's something I've learned to do over the years, and it's something I've counselled students on during my time at Lynchburg College. I've written a couple dozen research articles in my life, including a long review article, and I've written a book for the general public. But how to describe writing in a talk? That was definitely out of my comfort zone! Like any challenge I face, I embraced the task before me and thought about how I could describe good journal writing in a 50-minute talk. Writing for me is so discombobulated at times. I jump right in, write a few paragraphs in what will eventually be the middle of the paper, and then I do something else. The main struggle in preparing today's talk was how to present something nonlinear in a linear way. Whether I succeeded or not is up to the audience. The audience, by the way, was great! I got lots of though-provoking questions. At least half the audience spoke English as a second language. I admire those people because not only are they bilingual, something I wish I could join my wife in being, they are making wonderful strides to improve their English and publish the exciting research work they do. It has to be daunting to express thoughts and ideas in ways one is not accustomed to doing. My colleague, Zing, was gracious enough to snap a couple of photos of me while I was giving my talk. The one below shows me just getting going (click on the image for a larger view).
I wish I had a better way to hold my reading glasses, but the top of my head is what works for me! It was fun giving a talk on a new topic, one I'd not thought of as a talk topic before I was asked to make it a talk topic.
After getting turned around in the fog a couple of weeks ago, I made another attempt to see the beautiful sights atop the rocky promontories on Hathersage Moor. My wife, younger daughter, and I experienced a lovely day in the Peak District this past Sunday. No fog got in our way! We began our hike southeast of where the A6187 meets up with the Burbage Brook. Carl Wark was our first destination. My younger daughter likes to describe herself as a mountain goat because of her skill navigating over and up rocks and boulders. She's certainly our family's best climber! I snapped a photo of the Hathersage Moor while on the way down from Carl Wark (click on the image for a larger view).
We then made our way to Higger Tor. The photo below was taken from Higger Tor and shows Carl Wark to the left (click on the image for a larger view).
Is that a gorgeous view or what?!? We had no climbing equipment, so we avoided the sheer rock faces and hike up the scattered boulders. That might have been more fun than climbing with ropes. We had to think about which path to take and where to step. My daughter did a great job leading her proud dad up to the top.
Not content with two promontories, we left Higger Tor and hiked up to Stanage Edge. The photo below shows millstones made from gritstone and some of the sheep we met on our hike (click on the image for a larger view).
We had a lot of fun walking through the tall bracken; some of it was as tall as my daughter.
The walk back gave us a couple of interesting moments. I was leading my daughter as we neared the Burbage Brook when I stepped in a sink hole. Before I knew it, I had mud a few inches above my boots. I didn't panic and sink any more than that, and I was able to get myself out. I'm glad my daughter wasn't leading; she would have sunk in to her knees at least.
We had to jump across the Burbage Brook. I did fine, but my daughter slightly lost her nerve as she jumped from the bank. I caught her, but her trailing boot landed in the water. I pulled her out quickly. She then sat on a boulder and took off her boot. I couldn't help but laugh when she turned her boot over and a bunch of water spilled out. After all that fun we had a great meal at the Fox House pub. We've never had a bad meal there!
The votes were tallied and nearly 52% of those votes supported the UK leaving the EU. I knew the vote would be close -- all polling leading up to the vote suggested as much -- but I confess I'm surprised that "remain" didn't carry the day. These are strange political times we live in. Both left and right have serious divisions with them. Here in England, I've heard isolationists on the right who fear the "other" side with some on the left who want to blow the establishment system up, thinking that starting over is the only way revolution will happen. Strange bedfellows indeed. While on a recumbent bike at the gym this morning, I watched on live television the British Prime Minister resign. That David Cameron would leave isn't a shock, but it was something else watching it happen in real time. He'll likely leave in October. My family picked an interesting year to be in England! We'll leave an England at the end of July that will be rather different from the one we'll visit if we are lucky enough to return in the future. The Brexit vote reminds me of just how divided people are on certain ways of viewing the world, and how the groups rarely intermingle. I admit that I wanted the UK to remain in the EU, and essentially everyone I know here feels the same way. At least three times this morning I heard something like, "Everyone I know voted to remain. How did we lose?" While working at a university, I primarily interact with people in academia and professionals with "white collars." I simply don't cross paths with the large number of people in Sheffield who work "blue collar" jobs in various industries. I certainly don't view one group as being better than the other; my career choice has put me in proximity with one group. I learned this morning that Sheffield voted to leave by a margin of 51% to 49%, meaning the people I associate with were part of the minority opinion. I've heard much talk about there being "two Americas" in the US. We will have a choice this November between two candidates who poll at #1 and #2 historically on how much they're despised. And both have earned those rankings. But people who support one candidate can hardly fathom the thinking going on inside the heads of those support the other candidate. I can't help being like that myself. It has always been a complete mystery to me why so many in my country support citizens owning semi-automatic (or fully automatic) weapons. And that's just one example of many that make me feel like I'm part of one of the two Americas. It will be interesting to see how everything unfolds as the UK moves forward. We'll certainly be keeping up with UK politics after returning to the US.
There was no way I could attempt to stay up all last night and watch the deciding game of the NBA Finals. The game here began at 1 am today. So I made sure to enjoy myself all of yesterday for Father's Day. I've been called "son," "brother," "husband," and "uncle" in my family life, the latter of which has been particularly fun. In my professional life, I've been called "doctor" and "professor," though I've never liked all those titles. The one title I love above all others is "daddy," which has evolved to "dad" as my girls have gotten older. Hearing "dad" always makes me happy and represents the best way a part of me can live on after I die. My wife and daughters know how much I love the Peak District, so we all went to Hathersage for a little walking and a visit to a great country pub. Because my older daughter has a broken left pinkie toe, we kept walking to a minimum. Walking the countryside was still a lot of fun (click on the image for a larger view).
I never tire of the lush green grass on the English countryside. We walked along River Derwent for awhile before crossing it to get to a pub (click on the image for a larger view).
After walking got our appetites ready for a pub visit, we nipped into The Plough Inn. We had wonderful food there, including delicious desserts that should be reserved for special occasions only. Give The Plough Inn a try if you're ever in Hathersage.
My wife and daughters gave me a great Father's Day yesterday, though every day feels like Father's Day when I'm fortunate enough to hear my daughters call me "dad."
