Event overview
The Tahoe Rim Trail Endurance Runs are scheduled for July 18-19, 2026. The event will include the return of the TRTER 100 mile and 100K races, along with a 50K. Registration details are to be announced.
In 2025 the 100 mile and 100K races were not held because of reconstruction projects at Marlette Dam and the flume pipeline in the Spooner Lake backcountry. An alternate 50K course was offered in 2025.
