Race fuel
Over 100 km a gel every 40 minutes stops being a plan: most runners eat real food at the aid stations and take gels between. Practise what you will eat on your longest runs.
Our pick: SiS BETA Fuel gel, box of 6, strawberry and lime. 40 g of carbohydrate a gel, about twice a usual gel, from two kinds of sugar your body takes up side by side. Enough for race day and two test long runs.
Easy to forget on race morning: pack them with your bib the night before.
