Marine Corps Marathon Pace Calculator & Race Plan
The Marine Corps Marathon runs through Arlington and DC, finishing at the Marine Corps War Memorial. The course has some rolling hills and one soul-testing stretch on Hains Point around miles 17-20 that's flat but exposed and mentally tough with no crowd support.
October weather in DC can be perfect or unexpectedly warm. The model accounts for the rolling terrain and the weather, and gives you realistic splits for the back half when Hains Point and the late hills combine with fatigue.
