We are extremely pleased to hit such an unpredictable and challenging stage to better than 3%! Of the 175 cyclists who finished today's stage, 32 (about 18%) beat our predicted time today. Riblon's average speed is given below.

Of all this year's Tour de France stages, this is the one we thought our model would get too fast. I'll explain in tomorrow's post why I think this stage should be won in a time that goes over six hours. If tomorrow's winner sneaks in under six hours, I'll be writing about top speeds again.
Froome gained nearly a minute of time today over Contador for the overall classification lead. Will anyone catch Froome tomorrow???
