Negative Split Fueling Plan

A negative split fueling plan takes carbs and fluids early so late-race acceleration has fuel—matching negative split pacing, not starving the first half.

A negative split fueling plan front-loads carbs and fluids in the first half of a race so glycogen and blood glucose stay high when pacing accelerates—mirroring negative split pacing strategy. Skipping early stations to bank time often causes late bonks.

Set hourly grams before mile one, not when tired. Practice with negative split long runs.

Common questions

  • Does negative split pacing mean less fuel early?

    Opposite—you need early fuel to support a faster second half. Pacing discipline and nutrition discipline both start conservative on speed, not on calories.
