Tahoe Rim Trail Endurance Runs, live.

High trails on the Nevada side of Lake Tahoe

The Tahoe Rim Trail Endurance Runs start from Western Nevada College in Carson City on Saturday 17 July 2027, with four distances from 23K to 100 miles.

TRTER is a non profit event whose proceeds support the Tahoe Rim Trail Association's trail work and other community groups. The races run on high alpine and sub alpine single track and dirt roads in the Carson Spur of the Sierra Nevada, on the east side of Lake Tahoe. Every distance starts and finishes at Western Nevada College at 4,888 feet, the lowest point of the course, and the course averages about 8,000 feet.

The 100 mile race starts at 5:00 am with a 36 hour limit, finishing by 5:00 pm on Sunday. The 100K and 50K start at 6:00 am and the 23K at 7:00 am. The 100K has a 24 hour limit and is a Western States qualifier for a finish under 20 hours. The 50K climbs Ash Canyon to Snow Valley Peak, loops around Marlette Peak from the Hobart aid station and returns on the newer Capital to Tahoe trail, while the 23K turns around at the Waterfall aid station.

Nights on the course can drop to the low 30s even in July, and the finish in Carson City can be hot. Drop bags are allowed at Hobart, Tunnel Creek and Diamond Peak for the 100 mile and 100K, and pacers can join 100K runners at Diamond Peak.

Registration opens on 6 December 2026. The organiser publishes updated GPX files and course maps for 2027.

On Livebib you can follow a participant who chooses to share their own live position from the phone they carry. This is not the organiser's timing, and official results come from the Tahoe Rim Trail Endurance Runs.
