Registration:  Registration opens October 1st.

Qualifications to register: On the entry form, you must list a completed trail ultra that demonstrates you have the ability to safely navigate the day’s challenges. This is for safety’s sake, as well as to make reasonably sure that you’ll have a shot at making the cut-offs along the course. We accept trail ultras over marathon length.  If you enter without this qualification, your entry may be delayed or denied. If you have questions about your qualifications, please email ZaneGrey100K@gmail.com.

Race management may add additional entrants through sponsor exemptions, previous volunteer contributions and to add to the quality of the competitiveness of the event.
