Mountain Fuel

Mountain Fuel makes sports nutrition for running, cycling, triathlon and other endurance sports, including Sports Jellies and flapjack bars designed as a system for energy and recovery, and features testimonials from runners such as Kilian Jornet and Jon Albon. Based in Keswick in the Lake District, it was founded by former soldier Darren Foote, who found no effective, stomach-friendly nutrition system during his army service. It says it was the first company to specialise exclusively in balanced supplements for extreme and endurance sport, developed through nearly two years of research and field trials. It supported the Montane Lakeland 50 & 100 in 2016.

Precision Fuel & Hydration

Precision Fuel & Hydration develops electrolyte supplements and personalised plans for endurance athletes to manage fluid, sodium and energy intake. Founder Andy Blow says the business launched in 2011 after he explored sweat testing and individual differences in sodium loss during long-distance triathlon. The company says it has provided hydration services to professional teams in football, rugby, American sports leagues and motor racing, as well as endurance athletes; those are historical service claims, not a current sponsor list.

Torq

TORQ develops endurance-sport nutrition and offers fitness consulting. Its 25-year history says sports-science graduate Matt Hart founded the business in 1999, with support from his wife Sasha. The company describes an evolution from fitness coaching to energy products for endurance athletes; its nutrition claims are its own and users should check ingredients and serving guidance for their needs. A company milestone is not clinical proof of a particular product's performance benefits.
