- Stage 3: 4h 42' 58" (actual), 4h 47' 16" (prediction), 4' 18" slow (1.52% error)
I can't complain about a 1.52% error! Sagan's average speed is given below.
- Stage 3: 11.60 m/s (41.77 km/hr or 25.96 mph)
Tomorrow's Stage 4 is a 214.5-km (133.3-mile) long flat stage, which begins in the commune of Abbeville and ends in the capital of Upper Normandy, Rouen. Much like Stage 3, my student, Brian Ramsey, and I had to fill in some geographic data not seen on the Tour de France website's stage profile. The model I describe in Chapter 4 of my book requires geographic data to create inclined planes of the terrain. Some of the stage profiles for this year's race were in dire need of additional geographic information. Our prediction for Stage 4 appears below.
- Stage 4: 5h 10' 00" (prediction)
Will Fabian Cancellara hold the yellow jersey after tomorrow? We shall see!
