About Fuelstate

Fueling deserves a plan of its own.

Fuelstate exists to close the gap between planning race nutrition and following it when the miles get hard.

Why Fuelstate exists

Every split gets planned. Fueling still gets left to memory.

Runners can spend months preparing for a race, then rely on a rough interval, a note, or last-minute arithmetic for the nutrition plan. Fuelstate was built around a different idea: make the important decisions before the start, then keep that strategy useful when fatigue makes every decision more expensive.

Fuelstate is a running nutrition planner and live fueling companion for iPhone and Apple Watch. It connects the runner, the run, the conditions, and trusted products to preparation, packing, and race-day follow-through.

The product principle

One strategy from the clear-headed miles to the hard ones.

  • 01
    Personal to the runner

    Build around the run, the conditions, and products the runner already trusts.

  • 02
    Practical before the start

    Turn the strategy into preparation and a kit that can actually leave the house.

  • 03
    Useful during the run

    Carry the prepared plan into the race instead of asking the runner to memorize it.
