Great Day for Team Sky!

Brit Chris Froome dominated the final climb today to win Stage 7 of the Tour de France.  He bettered last year's winner, Cadel Evens of Australia, on the last, grueling uphill toward the finish line.  Below is the comparison with our prediction.
  • Stage 7:  4h 58' 35" (actual), 5h 13' 07" (prediction), 14' 32" slow (4.87% error)
Our error is lower than yesterday's, but I still remain amazed by how well cyclists have done over the past two days.  Their power outputs have exceeded what we've used in our model.  Don't let it slip your mind as you watch these cyclists that you are watching the best of the best.  There is no way I could have looked respectable on my bike on Stage 7's final climb!

Froome's average speed is given below.
  • Stage 7:  11.11 m/s (39.99 km/hr or 24.85 mph)
Bradley Wiggins, Froom'e Team Sky teammate and fellow Brit, now has the yellow jersey.

Tomorrow's medium-mountain Stage 8 begins in the city of Belfort and takes cyclists 157.5 km (97.87 miles) southeast to the Swiss town of Porrentruy.  There are lots of great climbs in the Jura Mountains in this stage (click here to see the profile on the Tour de France website).  The stage ends on rather flat terrain, so look for a great sprint to finish things off.  Below is our prediction.
  • Stage 8:  3h 57' 04" (prediction)
Based on how cyclists have done so far, I think the winner can cross the finish line in under four hours.  Will Team Sky keep the yellow jersey?


  1. Eric, Team Sky looks fantastic and will defend the yellow jersey, but I would like to see Yanez Brajkovic get out in a break and hold on to win the stage in a time of 3h50'40", which will be a little faster average than yesterday.

  2. Bob,

    Not a bad time prediction, but I'll take mine on this particular stage! It's always fun to hit the times with errors under 1%. We are predicting a fast time trial tomorrow. I hope we aren't too fast!
