“I use Sports Jelly for my races, they are a great product... soft flavour and the consistency is great, even without water and it doesn’t feel like a paste in the mouth.”

Kilian Jornet, World Champion Endurance Runner Jan 2020

“I love Mountain Fuel, particularly when I use the whole system on race days. The Sports Jellies are the best gels I’ve ever used and the flapjack bars are so much easier to eat on the run than other bars I’ve used.”

Jon Albon, World Trail Running Champion / Obstacle Race World Champion

I use this during ultras either in drop bags or with road support and find it to be really good at helping keep energy levels balanced and to replace lost fluids. I find protein bars can be hard to digest so having it in liquid form is v helpful. I think It tastes more like chocolate milk than an energy drink, doesn't taste too artificial and dissolves quickly in a sports drink bottle.

I use this after big gym workouts as a pudding after dinner. Sweet enough to feel like a treat but not so sweet you wouldn't want it on an ultra. I take a few in my pack for longer events and mix them at aid stations. Extreme Energy early in events, Recovery sachets and Jellies later on.

I love this product. Provides a massive dose of energy in a ridiculously tasty package. I use this before big gym workouts, long runs and Tris - it's reliably given me a second, third and forth wind on numerous occasions.

This is brilliant, just that hint of a flavour which is so much better than many other brands overly sickly sweet drinks which means it is my go to on ultras, never fails to go down easily and helps keep fuelled when solid foods may not settle when many hours into an event. Great stuff. MF contact and service is always spot on.

I have been trying various energy drinks for long-distance running and have struggled to find something that doesn't taste too strong or sweet. Mountain Fuel's tropical energy drink is perfect and easy to drink on long rums whilst giving me the energy I need.

Lynne Joseph · 3 months ago ·

One thing I can always say about Mountain Fuel is the product and service is top notch.
It’s my go to race fuel, tried and tested and part of my regular race routine!

Leigh Hunt · 3 months ago ·

I don't use anything else now for longer runs and rides. I can stomach sweet stuff beyond about 20 miles, but I can use mountain fuel all day without any issues. It also encourages me to drink as its so easy to drink and tastes great. The science side of things seems to hold up too, great for energy levels and hydration, even when running ultras

Have been using the energy sachets during long training runs and recovery afterwards. Been working really well

really nice taste and no powdery / gritty feel to it

The Raw fuel combined with the MF jellies were my go to on the Peak District marathon at weekend.
The Raw flavour is so subtle to your water but can definitely feel the benefits whilst using not only pre-race but also on the go. Definitely kept me hydrated and fuelled well to get round in horrible conditions!
The jellies were my go to for the push in the last 10km when energy levels were depleting. Highly recommend
