2026 Mount Rainier Half Marathon & Trail Events

The Mount Rainier Half Marathon begins at the summit of Crystal Mountain, treating runners to a spectacular point-to-point descent through the Cascade Range. With the iconic volcano as a constant backdrop, the course winds through old-growth forests, alpine meadows, and rocky ridgelines. The event, now in its fifth year, draws around 800 runners from across the country, many returning for the unparalleled scenery.

Runners trade pavement for soft dirt and rocky singletrack, with gentle and challenging inclines that reward with vistas of sparkling alpine lakes. The race is held in late summer, with ideal temperatures in the 60s and low humidity. While the field is modest, the energy is high — the gondola access and post-race expo add to the mountain-town charm. About 6% of participants are repeaters, a testament to the race's growing appeal.

The downhill profile — from summit to base — makes for a fast, memorable finish. Runners are rewarded with a finisher's shirt and the chance to celebrate at the base lodge. For those seeking a destination race with genuine mountain character, this half marathon delivers.
