About

Built for people who move.

We sell one thing, energy gels, in three lines. Everything else on this site is about using them well: how they work, when to take them, and how to train your gut before race day.

Built for people who move.

We sell energy gels and nothing else, on purpose. One product category means we can go deep rather than wide: every guide in the education hub, the fuel calculator and every journal article is about one job, getting carbohydrate into a working body without upsetting it. Original Energy Gel for everyday training, Liquid Energy Gel when you would rather sip, Roctane Energy Gel for the long, hot and hard days.

The gels themselves are made by GU Energy Labs in Berkeley, California, the company that made the first energy gel in 1993. Every packet is 100 calories, and we stock them as they are: three lines, 30-plus flavours, with and without caffeine. They run the lab; we run the shop and the fuelling guide.

In short

Three gels. One job.

Everything we stock, in three numbers. The 100-calorie packet is the point: small enough to take often, so you can keep feeding.

  • 3 gel lines: Original, Liquid Energy and Roctane
  • 30+ flavours across the three lines
  • 100 kcal in every packet, whichever gel you pick

Start with the gel that fits your day.

Original for everyday training, Liquid when you would rather sip, Roctane for the long, hot and hard ones. New to gels? Start with how to fuel.
