I was watching the final miles of a sprint stage of the Tour de France on TV earlier this week. On a relatively flat road, the front guys like Fabian Cancellara were pushing about 40 mph! That’s insane. While they can’t sustain that kind of speed over long distances, it’s astonishing that they can even get up to that speed on a flat road.
On the mountain stages, I think some of the riders approach 60 mph or even faster. You’ve got to be fearless to be doing that on a bike.
