How To Fuel

Sometimes it can be hard to know how much and when to eat on a long run or race. Rule of
thumb - aim to consume 40-50g carbs and 200 kcal per hour. Top tip - set your watch to
beep every half an hour to remind you to eat regularly and stay consistent.
Sports Jelly - 20g per sachet
Feel Good Bar - 40g per bar
Energy Fuel - 40g per sachet in water
Example - If you are running for 4 hours you will need around 180g of carbs. You could make
this up from:
- Jellies x 5 = 100g
- Feel Good Bar x 1 = 40g
- Energy Fuel x 1 = 40g
Above is a guide only, everyone is different and weather can also affect how much fuel we
need. We would recommend you always carry extra as emergency calories.
We have some guides from Rupert Bonington at Mountain fuel for some of the most popular
products.
