The Tour de France Diet: How to Consume 8,000 Calories a Day. Cyclists on the Tour de France need to consume some 8,000 a day to keep weight. At rest, we all burn roughly 90 calories an hour, or a little more than 2,100 a day. Run at full-tilt on a treadmill for an hour, and you'll burn some 600 â although most of us can keep it up for half of that time.
