About Us

We’re three friends, united by a love of endurance sports, a strong dislike for overpriced gel sachets, and a shared belief that running/cycling/swimming ridiculous distances for “fun” is totally normal.

Born somewhere between a half marathon, a cold swim, and a long ride where someone crashed and burned...hard, Replen started as a simple idea:
What if we made a sports supplement that was actually affordable, didn’t destroy the planet, and didn’t taste bad?

So we bootstrapped it. No funding rounds. No flashy offices. Just a bunch of spreadsheets, some very sticky kitchen experiments, and a few hundred test runs (literally) later - Replen Endurance Hydro-Gel was born. It’s packed with carbs and electrolytes, fits into a reusable flask, and doesn’t leave you or the environment wrecked after use.

We’re obsessed with triathlons, trail runs, and open water swims, but more than anything, we’re here to help everyone - from weekend warriors to couch-to-5K hopefuls - believe they can go further than they think. Whether you're chasing a podium or just chasing your kids around the park, Replen fuels your mission.

Oh, and we still do all the packing and shipping ourselves, so if your label is a bit skew, blame the guy who ran intervals that morning.

Fuel. Perform. Replen.
(And look cool doing it.)
