“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

Mountain Fuel Sports Nutrition System

The seven-product multi flavour system has been designed to be used in conjunction with each other, however you can use any of the products individually depending on your exercise regime, intensity and duration.

1. Night Fuel can be enjoyed the night before your event/activity; it has been specifically formulated with essential ingredientsrequired by the body for it to replenish while it rests. Simply mix with hot milk or water to give a tasty Chocolate flavoured drink. Slowly sip during the evening to allow your body the optimum time to benefit; just because you’re asleep doesn’t mean you can’t prepare your body for the next day’s session!

2. Morning Fuel (available in Gluten Free) can be utilised at any time of the day – despite its name! By mixing with a little water or milk (hot or cold), use as your pre-event meal or shake. It has been designed to be nutritionally balanced, is light on the stomach, is quickly absorbed and tastes great. Depending on your event/activity you could add seeds, fresh/dried fruit or a small handful of oats. Morning Fuel can also be used to create tasty, power packed snacks to eat on the go while running or cycling. Gluten Free

3.  Xtreme Energy Fuel is not just your everyday sports drink as we ensure that we include all the ingredients required to deliver asustained energy release throughout your event/activity.

Ultimate Recovery Fuel can also be utilised mid-race by endurance athletes/triathletes to help replenish their muscles and offset muscle soreness. Prepared with milk or water, Ultimate Recovery Fuel comes in either Strawberry or Chocolate flavour. Gluten Free.

5. Sports Jelly Here at Mountain Fuel we could have easily produced like for like sports gels, however, we believe that our new product is a great replacement for energy gels, especially when training and competing in endurance events. The Mountain Fuel Sport Jelly with electrolytes is a hybrid of jelly and a drink, and the perfect option for those who like the idea of having a convenient but effective ‘food’option whilst still staying hydrated. Lightly flavoured these jellies are refreshing and come in three flavours Lemon & Lime, Orange and Cola with Caffeine. Gluten Free & Vegan

6. Ultra Chia Gel The Ultra Chia Gel is the perfect endurance fuel, delivering a sustained energy release by combining the finest natural ingredients. The Ultra Chia gels provide a delicious ‘wholefood’ feel that’s easy on the stomach, even at high intensity. There are two flavours to choose from Apple & Cinnamon and Raspberry. Gluten Free & Vegan

7. FeelGoodBars Our bars are delicious and nutritious but most importantly you can actually eat them on the go, unlike other flapjacks and bars that stodge up, are like saw dust or take an eternity to chew. The flapjack style bars are Vegan, Gluten Free and nut free and literally melt in your mouth in the first bite. They are energy dense yet easy on the stomach too and described as the tastiest and best bars ever by world class athletes! They come in three flavours, Double Ginger, Date and also a Turmeric & Orange. Gluten Free & Vegan
