The USA Pro Cycling Challenge, which begins in Durango, Colorado this Monday, is likely the toughest bike race in the world. Every stage but the last surpasses – often multiple times – the elevation of Col de la Bonnette, the highest point of the Tour de France; the thin air is unforgiving; and the total gain (42,000 feet) is equivalent to the maximum altitude of a Boeing 747. It’s also the most watchable road race on the planet, passing through such party towns as TellurideAspen, and Denver and, in between, through the most picturesque roads in the Rockies. If you’re not close enough to stop by from August 22 to 26, then make sure to put it on your calendar for 2013. Then, download the Pro Tour Tracker iPad app to watch it this year.
