After months of training for one of the World Marathon Majors, you want your race to go as smoothly as possible to maximise your performance.
When you are running for two hours or longer, your body uses a large number of carbohydrates for energy. If you do not have enough, you risk hitting the wall around mile 20.
Your body needs glucose, in the easily digestible form of carbohydrates, to quickly release energy.
Our ideal race day fuel for a marathon is the GO Isotonic Energy Gel and these will be available out on the route at Mile 12 and 18 today.
What’s your favourite flavour?
