Race fuel
One every 40 minutes, the orange marks on the profile, by the clock:
Under about 75 minutes most runners need no gel: water at the aid stations does it.
Over this distance most runners mix in real food at the aid stations; the gels cover the hours between.
For your long training 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.
Order by 30 October to test them on two long runs first.
