Here's the insane number of calories cyclists in the Tour de France burn on race day

On July 4, cyclists from around the world will begin the 102nd Tour de France, a prestigious, 2,087-mile, three-week-long race.

Each day, participants bike about 110 miles and burn roughly 6,071 calories, according to Inside Science, a science news site run by the American Institute of Physics.

To give you a better idea of just how many calories that is, we've teamed up with the folks at Inside Science, who originally calculated how many jelly donuts you'd have to eat to generate enough energy to keep up with a Tour de France cyclist on race day. Turns out it's 32!

Here are some more popular foods and how many of each you'd have to eat to compete. (Of course, this isn't what Tour de France cyclists actually eat while competing.)
