• Cross-country skiing is a demanding activity at the Olympic level. 
• US Olympian Jessie Diggins told INSIDER each hour of racing can burn off a Chipotle burrito.
• She's not wrong: elite skiers can burn more than 1,000 calories an hour when racing. 

Cross-country skiing is one of the most physically taxing sports at the Winter Olympics. The seven cross-country events at the games are so exhausting that many skiers collapse immediately upon crossing the finish line.

Pro skiers also move at a grueling pace — and burn a lot of calories. According to data from the Compendium of Physical Activities — a research-backed list of how many calories are burned by different activities — a 200-pound elite skier will burn about 1,3000 calories per hour when moving at 8 miles per hour or faster. A 150-pound skier will burn about 1,000.See the rest of the story at Business Insider
