How many gels for a 100km ride?

For a 100km ride, you would likely be riding for around 4 hours or more. In terms of fuel, aim for one Slow Release Energy Bar per hour and take some extra gels with you to top up supplies if you need it – especially before or after tough climbs. Drink at least 500ml drink per hour – such as Slow Release Energy Drink. You’ll need to bring extra powder with you to make up more drink – cafes or petrol stations are usually good places to top up bottles with water, so plan these stops into your ride. It’s always important to carry an extra emergency gel with you – more often than not you won’t need it, but it’s best to be prepared in case you go for longer than expected. Try gels with caffeine, such as Energy Gel Aqua Caffeine Hit, for an extra boost, especially for longer rides.
