The Marlette 50K is an adventurous journey through some of the world’s most scenic and challenging trails. Starting at Spooner Lake in Nevada’s Lake Tahoe State Park, this run showcases miles of epic trails and breathtaking views. Imagine a pristine Sierra single track surrounded by 360-degree vistas of Lake Tahoe, Marlette Lake, and the Carson Valley and Range.

The Marlette 10 Miler starts at Spooner Lake, looping around it before transitioning to an out-and-back on the Tahoe Rim Trail. The course completes its loop around Spooner Lake as it nears the finish. This beautiful run provides stunning views of North Canyon, Lake Tahoe, and Snow Valley Peak.

Several major infrastructure projects are taking place in the Spooner Backcountry through which our courses travel. One of the projects is the Marlette Lake Dam Resilient Infrastructure Project.

Due to the project, Nevada State Parks and Nevada Public Works have recently decided that several trails in the Spooner Backcountry, including significant sections of the Marlette 50K and most of the Marlette 10 Miler courses, will be closed to the public for the season.

We have identified alternative routes for 2025 that feature many of the typical trails for the Marlette 50K, Spooner Lake 5K, and 10K. The Marlette 10 Miler route is a new course entirely.
