The 50K course is an out-and-back route to the "No Post" Aid Station at the 15.5-mile mark. The 50 Mile, 100K, and 100 Mile courses continue along rolling hills and include two or four significant climbs, respectively. The 100-mile route crosses into Nevada. All courses finish back at the start line.
