About
The Tahoe Rim Trail Endurance Runs climb onto the Tahoe Rim Trail on the east side of Lake Tahoe, high enough that the thin air is part of the test, with a course topping out near 9,000 feet. The start and finish have sat in Carson City since a 2021 course change. The race puts that course at about 102 miles and 18,140 feet of climb, and its 100K at about 62.5 miles and 10,750 feet. It sells itself as a glimpse of heaven and a taste of hell, and shorter 50K and 23K races share the weekend.
The 100-mile starts at 5:00 a.m. and the 100K at 6:00 a.m. Both count as Western States 100 qualifiers: the 100-mile for a sub-36-hour finish, the 100K for sub-20, which is stricter than its own 24-hour cutoff.
Course
High-altitude loops on the Tahoe Rim Trail east of Lake Tahoe, starting and finishing in Carson City, with a high point near 9,000 feet. The race puts the 100-mile course at about 102 miles and 18,140 feet of climb, off a 5:00 a.m. start with a 36-hour cutoff, and the 100K at about 62.5 miles and 10,750 feet, off a 6:00 a.m. start with a 24-hour cutoff.
How to register
Registration is on UltraSignup, first come and not a lottery, but the 100-mile entry is gated: runners must meet the race's qualification standards by the time they register, and owe eight hours of volunteer work before the event. The weekend also holds 100K, 50K and 23K races.
