Race pace is simply your goal time divided by the distance, but how you distribute it matters. A negative split — starting conservatively and finishing faster — is how nearly every marathon world record is run, because going out too hard burns glycogen and invites the dreaded wall. Even pacing is the safe default.

Average pace5:41/km

Governing equation
Reading this result: Even pacing holds 5:41/km the whole way — the safe default, since pace is simply goal time (240 min) divided by distance (42.2 km).
