Crater Lake Marathon
The Crater Lake Marathon takes you around the rim of one of the most striking volcanic landscapes in North America, at altitude, on a course where the scenery competes hard with the effort required to finish.

Race-Day Weather
August at Crater Lake runs warm in the afternoons, with highs that can push into the low 90s. The morning start is much cooler, often in the mid-50s, so layers at the gun make sense. The real thing to plan for is the heat building through the back half of the race. You are at altitude and exposed on the rim, and the combination of sun and thin air makes the late miles harder than the temperature alone suggests. Hydrate early and don't wait until you feel it.
