Larch Madness Trail Races

Okanogan, United States • 18 Oct 2025

The Larch Madness Trail Races, held at Loup Loup Ski Bowl near Twisp, Washington, offer challenging trail running events amidst stunning fall scenery dominated by golden larches. Distances include 5K, 15K, 25K, and 50K, with elevation gains ranging from 1,300 to 18,200 feet. The courses feature steep climbs, rugged terrain, and significant off-trail sections, making them demanding even for experienced runners.

Aid stations provide hydration and snacks on longer routes. Dispersed camping is available at the start/finish area, supporting the local Loup Loup Ski Education Foundation. A festive post-race party celebrates participants with food and drinks.
