Everyone knows that I love tearing down terrible “formula for” stories, but hopefully this one of my own won’t receive the same treatment as it is actually based on some solid maths!

Marathon runners need never “hit the wall” again thanks to a mathematical model that will help them reach the finish line in their best time.

More than 40 per cent of marathon runners will hit the wall during a race, experiencing sudden pain and fatigue as their carbohydrate reserves run low and their body switches from burning carbohydrate to burning fat. So Benjamin Rapoport at the Massachusetts Institute of Technology has given runners an online calculator that will tell them how much carbohydrate they need to consume to have enough for a whole race.
