Gels for Yamanashi Prefecture, between the aid stations

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.

Easy to forget on race morning: pack them with your bib the night before.
