To celebrate the start of the Tour de France, cycling presenter and former racer Rebecca Charlton takes you behind the scenes at one of the world's biggest bike events to find the race is on in the kitchen to fuel riders who need to eat up to 8,000 calories per day for three weeks straight. She learns about Chris Froome's nutrition plan with Olympic coach and now Team Principal at Team Sky, Sir Dave Brailsford, she joins chef Sean Fowler as he cooks for the Groupama FDJ team as they fight for a place on the podium and she hears how the author of the Grand Tour Cookbook Hannah Grant had to battle to get her meals on the table in some of the worst kitchens imaginable.
