The difficulty of the terrain means this is NOT an entry-level race. Each potential participant will be reviewed by the race directors after we receive the completed registration.

If you have a race that is not a 50k but has a high degree of difficulty, it may be an exception to the above standard, just email us to find out if the race may qualify you. Be sure that your race is an official race with results published on a publicly available website. Timed races (12-hour, 24-hour, etc.) can not be used as a qualifying race. You must have completed a qualifying race before registering.
