For the third time, I entered the Tahoe Rim Trail 100 held in the mountains on the north-east side of beautiful blue Lake Tahoe. This race is in its 4th year. The course is laid out on state park and state forest land, climbing ridges overlooking beautiful Lake Tahoe and various reservoirs. The surface is mostly very runnable, soft single track. There is about 19,500 feet of climbs, aided by many switchbacks. Most of the course runs between 7,000-9,000 feet elevation. This race for some reason has a low finisher rate, but to me, this is an “easy” mountain 100 course.
