Custom Energy Gels · Built for Endurance Athletes
The first custom energy gel powder for runners, cyclists, and triathletes.
ReFuel Athletics makes custom energy gels mixed fresh to order. Unlike traditional running gels with one-size-fits-all formulas, every ReFuel pouch is built around your body, your race, and your fueling strategy. Choose your carb load, electrolyte balance, and flavor — we mix it in our facility and ship within 24 hours. Want caffeine? Our Race Day gel doses it precisely.
Whether you're training for a 5K, a marathon, an ultra, or an Ironman, the right endurance gel is the difference between bonking at mile 18 and finishing strong. ReFuel's custom marathon nutrition lets you dial in 20–90g of carbohydrates per serving and 100–500mg of sodium — plus precisely-dosed caffeine in our Race Day gel — every variable that affects how you race.
Why athletes are switching to custom energy gels
Generic energy gels were designed for an average athlete who doesn't exist. A 130-pound trail runner doesn't need the same fuel as a 200-pound cyclist. ReFuel gives every athlete a personalized formula based on their weight, effort level, race distance, and gut tolerance — built using current sports science research.
Endurance fuel that actually works for you
Our reusable gel flask replaces single-use foil packets — fill it from your custom pouch, twist shut, and run. It's BPA-free, dishwasher safe, and fits any race belt. One flask, infinite formulas, zero packaging waste at the finish line.
Made by athletes, for athletes
Founded by competitive runner Hayden Hooper, ReFuel is built on one belief: there should be no compromise between breaking records and eliminating waste. Every formula is grounded in sports nutrition research, tested by real athletes, and designed to give you a performance edge no off-the-shelf running gelcan match.
Subscriptions
One bag. Two months.
Less than a gel a serving.
We ship powder by the bag instead of packing single servings, so you pay for fuel rather than foil. Scoop what the session needs — 20g on an easy day, 60g when it counts.
