Chase golden larches up the Loup

Overview

As autumn paints the eastern edge of the North Cascades in molten gold, Larch Madness welcomes you to the secluded slopes of Loup Loup Ski Bowl. Towering larches flare against crisp blue skies while a carnival of crunchy leaves swirls around racers and supporters alike. Expect an energetic mountain-town vibe where cowbells mingle with pine-scented air and wood-fire smoke from the camp-circle after-party.

The course is equal parts thrill ride and character builder: steep jeep roads, rowdy ski runs, and rugged off-trail traverses keep your heart thumping and your senses firing. Finish strong, then refuel with Rainshadow’s legendary potluck feast while swapping trail tales beneath a blanket of stars.

Key Highlights

  • Loup Loup Ski Bowl on the eastern edge of the North Cascades

  • Combination of steep ski runs, rough jeep roads, and up to 45% off-trail sections

  • Loose dirt, rocks, rugged alpine terrain

  • Expect cold temps, possible snow, and slippery footing

  • High-traction shoes and trekking poles recommended for longer distances

Cutoff Time18HR, 1:00AM

Starting at the base lodge, each loop claws up Little Buck Mountain before diving down black-diamond ski runs that test every ankle turn and quad burn. The Blue Loop (5K) circles the resort perimeter, while the Yellow and Pink Loops stack vert with ruthless efficiency. Expect loose scree, grassy meadows dotted with larch needles, the occasional dusting of snow, and panoramic views that sweep from the Methow Valley to jagged North Cascade peaks. Shoes with sticky lugs and optional trekking poles are wise companions.

Loops

  • 50K athletes alternate Yellow and Pink loops five times before a final Blue victory lap
    25K racers tackle a Blue-Yellow-Pink-Yellow-Pink sandwich

  • 15K completes Blue-Yellow-Pink once

  • 5K conquers a single Blue

Aid and drop bags greet you at the lodge between every circuit, never far in distance, but sometimes ages away in effort.
