The Tahoe Rim Trail 100-mile Endurance Run takes place on high elevation alpine and sub-alpine forest single track trails and dirt roads in the Carson Spur of the Sierra Nevada Mountains. The event is located on the east side of Lake Tahoe. All distances begin and end at the Western Nevada College in Carson City, Nevada, which is at 4,888 feet and is the lowest point on the course. The highest point of the event is just below the summit of 9,214-foot Snow Valley Peak (which also provides one of the best views on the course). The course is marked with highly visible fluorescent orange flagging with a highly reflective tip.
