GUTR

Train your gut. Run your race.

Your legs won't quit.
Make sure your stomach doesn't either.

Every runner hits a wall. But for most of us, it's not our legs that give out first — it's our gut. Nausea, cramps, gels that just won't sit right. Race day shouldn't feel like that.

Why we built this

At the London Marathon, I hit the wall at 28k. And instead of soaking in the atmosphere of one of the best marathons in the world, it became a blurred, painful slog — and I immediately threw up on the finish line. Those poor event organisers!

The reason? I hadn't fuelled properly. And everywhere I looked, the advice was the same: “you need to train your gut.” Great. But nobody was telling you how.

How much? How often? When should you start? Does your weight matter? Your pace? Your age? What about hydration? GUTR answers all of it — a week-by-week plan built around your body, your gel, and your race. So your finish line looks a little different to mine.
