The Tour de France kicked off on Saturday and if you haven't seen parts of the race before, it's a heck of a test of endurance, speed, and tenacity. The world's top professional cyclists have spent years preparing to compete in the event, which is the most prestigious stage race in cycling.

The riders will cover 2,277 miles in 21 stages over 23 days (yes, that's a measly two rest days) and—get this—they'll burn a combined 19.8 million calories by the end of the Tour. That's a whopping 100,000 calories per rider. (Check out the video above to learn more crazy stats about the Tour de France, and head over to to learn more about the race, including where to watch it.)

But you don't need to own an expensive bike or go on a multi-day pedaling marathon to get the fat-melting, muscle-sculpting benefits of cycling. Mere mortals can still torch 500 calories per hour, all while boosting aerobic strength without impact on your joints.
