Lost Lake 25K, Bellingham WA

The Lost Lake 25K is a point to point trail race organized by Yeti Trail Runners near Bellingham, Washington. The course starts at the Lost Lake Trailhead and finishes at the Larrabee State Park Amphitheater. Distance is 25k.

The route runs through the moss-covered Chuckanut Mountains and through Larrabee State Park. Runners pass old-growth evergreens, alpine lakes, and exposed ridgelines. The course offers runnable singletrack, some technical sections, and no repeated out-and-back segments. On clear days the route can include views of Mount Baker, Bellingham Bay, and into Canada; on misty days the course shows typical Pacific Northwest conditions.

A downloadable course GPX and a pacing plan are available. Race timing is handled by Zen Arcade Timing, which provides chip timing with real-time tracking and live splits. Swag listed for finishers includes a custom race shirt and a custom finishers medal.

Aid station details will be posted closer to race day; the event notes that volunteers will provide support and that stations typically include water, electrolytes, and snacks. The venue is just outside Bellingham with nearby lodging and post-run options, and the start and finish are about 0.2 miles apart. Weather in the Chuckanuts can be misty and cool or sunny and dry, and trail shoes with good grip are recommended. Visit the organization's website for the most recent information.
