RocketFuel started on long training days and post-run debriefs between Roberto Zanon —a fiercely competitive ultra-distance runner — and his coach, Giannis Tzanetakis, an expert in sports nutrition. We kept hitting the same wall: nothing on the market let athletes micro-dose clean carbs with the exact ingredients we wanted, without the gut drama.

So we built the fuel we wished existed.

Giannis mapped the science—optimal glucose-to-fructose ratios, sodium done right, smart actives for focus—while Roberto stress-tested every iteration in real races and brutal training blocks. The result is a super-optimized, athlete-designed hydrogel system you can use anywhere: steady energy when you need hours, strategic surges when you need seconds.

From coach’s lab notes to finish-line proof, RocketFuel is our promise: simple, precise, race-ready fueling—created by people who live this sport.
