Portland Marathon pacing strategy

A runner report calls the course relatively flat, with a maximum height of 178 ft, but the official site names a climb at Reed College and bridges add short rises. Run the climbs by effort and keep the rest steady.

Pacing by course section
Section	Terrain	Advice
mile 1–6	Downtown start and early bridge crossings	Start at goal pace or slightly slower.
mile 7–20	Mid-race neighbourhoods and bridges	Hold even effort; slow slightly on rises.
mile 21–26.2	Climb near Reed College, then back to the waterfront	Keep form and push in the last mile.
