A 70kg rider pedalling hard burns approximately 1,000kcal per hour. Riders in this year’s Tour de France will cover 3,328km, and if we assume an average speed of 40kph, that’s 83 hours of riding – burning in the region of 83,000kcal, or 4,000kcal per stage.

I wanted to find out how they do it and just how difficult it is to keep up with the vast energy demands of the race. So I decided to find out – by…
