Does the Tour de France ring a bell? The annual race through France is one of three European Grand Tours. The other two are Giro d’Italia and Vuelta a España.

They are all 3 weeks long and involve back-to-back days in the saddle with a mix of individual and team time trials, mountain climbs, and sprints totaling more than 3,000 km (that’s more than 2,000 miles!).
