How much you need
Carbs an hour, by race
Small and often works best: one or two pastilles every 15 to 20 minutes.
Two Energy Pastilles are 30g of carbohydrate. One scoop of Power Fluids is 27g. These ranges follow widely used sports nutrition guidance; practise your amounts in training before race day.

What runners say
“I have used FTP powder and pastilles for my last 2 marathon training cycles and race days as I find them easier to take than gels and easier on my stomach.”
“Used them during my training and on race day at the Yorkshire marathon. Found them a lot easier to digest than the gels.”
“Managed to get 60g carbs per hour for the first time (1 pastille every 15 min - or 2 together if I forgot!).”
“The best way to carry the pastilles. Thankfully I've found a product that doesn't leave my running vest sticky!”
