What to eat to run a marathon

What should runners should eat to train for, and complete, a marathon? With major races like the London and Boston marathons approaching, more people than ever are taking on the 26.2-mile challenge. But what should you actually eat to fuel that distance? Ruth Alexander is joined by one of the most successful marathon runners in history, Paula Radcliffe, who held the women’s world record for 16 years. She shares what it takes to fuel months of marathon training, and what it feels like when things go wrong during a race. Also on the programme is former world champion runner Steve Cram, now a coach and commentator, who explains the common nutrition mistakes he sees among recreational runners. And Performance Director of the dsm-firmenich Running Team, Valentijn Trouw tells us what it’s like to oversee the performance programmes of elite athletes including marathon legend Eliud Kipchoge. Ruth asks them what runners should fuel their training, what to eat in the crucial days before a race, and how to avoid “hitting the wall” on marathon day.
