1ooK Qualifier: To be able to run the 100K, runners must have completed a 50K distance (or greater) race in the past 3 years (from November 1, 2014 to June 23, 2018).


 Ultra Signup logo

The 2018 100K IS FULL and there is no open waitlist.  HOWEVER, there is still a path into the 100K:

–We will allow anyone registered for the 55K to upgrade to the 100K IF SLOTS OPEN UP (Race Day Limit = 100).  This will be on a FIRST COME FIRST serve basis. 

–Each year due to unforeseen issues (injury, lack of training, commitments, etc…) some 100K runners drop to the 55K or out of the event entirely. Thus opening spots. 

–If a 55K runner wishes to move up please send us an email letting us know ( When a slot opens we will send the next listed runner information on how to change distances. When runners move up or down in distance, all paid shuttles are transferable.

–There is no guarantee if you get on the internal waitlist that you will be able to move up.

–Once the 55K distance fills all registration into the race will cease. There will be no 55K open waitlist.

A percentage of the registration fees will be donated to local cross country teams.
