The Tour de France is the most gruelling cycling endurance event in the world and the number of calories each of the 198 cyclists has to consume per day as part of their Tour de France diet, is equally intimidating – up to 8000 (the average recommended daily amount for males is 2500). The legendary race, which this year takes place from 2 to 24 July covers over 2000 miles in 23 days. There are 21 stages in total this year: nine flats, nine mountain stages, two time trials and one hilly stage. And guess what, just two rest days. No wonder the Tour de France diet is so extreme.
Let’s put the energy expenditure of these super-athletes into perspective and check out the 2016 route below:
25 million
Total calories burnt by all the riders over 21 stages.
6000 to 8000
Calories burnt per day by each rider.
1100
Grams of carbohydrate consumed by each rider per day on average.
60
Number of bananas each rider would have to consume each day to roughly meet energy expenditure; or around 30 jelly doughnuts.
10
Number of litres of water a day consumed by each rider.

Below is a sample Tour de France diet plan (via Cycling Weekly) and at the bottom you’ll find a video of Norwegian journalist Nikolay Ramm very foolishly attempting to consume an entire day’s Tour de France diet in one sitting.
