The Tahoe Rim Trail Endurance Runs (TRTER) 2026 is a popular annual trail running event on the scenic Tahoe Rim Trail. This 165-mile trail circumnavigates the stunning Lake Tahoe in California and Nevada. Here at Strambecco, we consider it one of the Best Trail Running Events in the Southwest.

The event includes multiple distances for runners of different abilities and experience levels, including 100 miles, 56 miles, and 50k, while all are challenging. Each event starts at Western Nevada College in Carson City and on single-track trails and dirt roads with spectacular views of Lake Tahoe and the deep valleys of the Great Basin. Many miles are run on the Tahoe Rim Trail in the Spooner backcountry of the Lake Tahoe Nevada State Park and on the Toiyabe National Forest land. Western Nevada College is located at 4,888 feet of elevation, and the highest point of the course reaches 9,214 feet.

The Tahoe Rim Trail Endurance Runs courses feature challenging terrain, including steep climbs and descents, rocky trails, and technical sections that require runners to be skilled and experienced in trail running. Along the way, runners are treated to breathtaking views of the lake and the surrounding Sierra Nevada mountains. In July, runners can expect warm temperatures during the day and cool temperatures at night. Several well-stocked aid stations along the course offer food, water, and other supplies.

There is nothing simple about the 100-mile course. It will be closer to 102 miles with approximately 22,000 feet of elevation gain. Running a 100-mile, 50-mile, or 55K race is a true challenge physically, mentally, and emotionally. Don’t expect to run a PR here. DO expect to find the finest aid stations in ultra running, epic scenery, and world-famous volunteers!

The event organizers take great pride in providing a range of amenities for participants pre and post-run. These include fabulous food trucks, where registered participants can enjoy delicious meals and refreshing beverages from the Ultra Lounge, all included in the entry fee. For relaxation and comfort, there is the Ultra Lounge, featuring tables, kick-back chairs, massage services, and soaking buckets.
