About This Race
The Tahoe Rim Trail Endurance Run traces one of the most scenic high-altitude trail systems in North America, circumnavigating Lake Tahoe through the Sierra Nevada and Carson Range mountains. Set at elevations ranging from 6,200 to over 10,000 feet, this race showcases the pristine wilderness that surrounds the alpine lake, offering runners panoramic views across the crystal-clear waters and surrounding peaks. The course follows the renowned Tahoe Rim Trail, a 165-mile loop that connects diverse ecosystems from dense forests to exposed granite ridges. Runners navigate through multiple wilderness areas, including portions of the Desolation Wilderness and Mount Rose Wilderness, encountering everything from technical rocky sections to smooth singletrack. With 20 aid stations strategically positioned along the route, the race provides comprehensive support for the 36-hour journey around the lake. Limited to 150 participants for the 100-mile distance, this event also offers 50K and 100K options, making it accessible to runners at different stages of their ultra careers. The early July timing typically provides ideal mountain running conditions, though runners should prepare for potential afternoon thunderstorms and significant temperature variations between dawn starts and midday sun at altitude.
The course follows the complete Tahoe Rim Trail, a well-maintained singletrack path that circles Lake Tahoe through diverse terrain. Runners traverse dense coniferous forests, open meadows, and exposed ridgelines, with significant stretches above treeline offering unobstructed lake views. Technical sections include rocky descents and root-strewn forest floors, while smoother segments allow for faster running through pine and fir corridors.
Key landmarks include the climb over Mount Rose Summit, passages through Desolation Wilderness, and the traverse of the Carson Range. The trail surface is predominantly natural singletrack with some fire road connections, requiring navigation skills in certain wilderness sections where trail markers may be sparse.
