Amateur athletes rarely get a chance to measure themselves against professionals. But with cycling, many pros and amateurs do the same thing after a ride: They upload their trip to an app called Strava, where anyone can see and track their speed and location. While they are not technically racing together, the data does allow us to see just how much faster the pros are than the rest of us. We created a virtual race of sorts, taking some of this year’s fastest Tour de France cyclists who posted their rides to Strava and pitting them against a few hundred amateurs who rode over the same climbs and posted their results online.
