I’ve been following the Tour de France
According to the New York Times article, “Five-star tour cuisine for guys who eat and ride” the men on the tour require 5000 to 8000 calories a day.
Every day at the Tour, Fowler cooks exclusively for Garmin’s nine riders, to the chagrin of team management. (…)
On a typical morning, they will gather their cooking gear and take it to the motor home in which they follow the race. They make sure to arrive early at the team’s next hotel, to inspect the kitchen.
If it is not up to Sean Fowler’s standards for cleanliness, which has happened a few times at this Tour, he will cook in the motor home. He takes precautions to keep the riders safe from food poisoning or other gastrointestinal problems, which could be devastating to their performance. In his motor home, he wields utensils and pots and pans like a careful samurai because the space is cramped.
