How do I fuel?

Carbs, fluid and sodium per hour for race day, mapped to your goal pace and time on course, so race day is rehearsed rather than a gamble.

The coach's read

For a 3:14:40 marathon, aim for about 65g of carbs an hour from the start, not when you're already empty. Practise it on your long runs so your gut is ready on the day.
