Bilbao is on the right; Mühlberger is on the left. I was stunned that the winning time came in under five hours. Our prediction wasn't great.
- Stage 12: 4h 57' 53" (actual), 5h 23' 17" (prediction), 25' 24" slow (8.53% error)
We were nearly perfect on the first mountain stage, which was the grueling Stage 6 with its category-1 climb finish. That stage was 49 km (30 mi) shorter than today's stage, but the top cyclists today output 13% more power today than during Stage 6. Were they holding back on Stage 6, going crazy today, or is there a better explanation? This really has been a fascinating year for modeling the Tour de France! Yates's average speed is given below.
- Stage 12: 11.72 m/s (42.20 kph or 26.22 mph)
I love watching the mountain stages. Check out Tim Wellens crossing the top of Col de Peyresourde (click on image for a larger view).
A little later, Simon Yates and his two finishing companions were first atop La Hourquette d'Ancizan (click on image for a larger view).
On the first big descent, speeds reached over 90 kph (56 mph). I just can't imagine going that fast on a bicycle. And of course scenery was spectacular in the Pyrenees. Check out one of the valleys on the final descent (click on image for a larger view).
The Tour de France is quite an advertisement for visiting France!
Tomorrow's Stage 13 is an individual time trial. The 27.2-km (16.9-mi) route begins and ends in Pau. Riders will loop south and then back north during their rides. Our prediction is given below.
- Stage 13: 34' 52" (prediction)
Will there be a shakeup in the general classification tomorrow?
