Registration is full.  Thanks for all of your kind and thoughtful notes in the applications.  We hope to have the roster published in a couple weeks as we wait for all successful applicants to accept entry and clear up a few stragglers.  If you had a qualifying race and were registered, you should have gotten an acceptance by now.

Registration will open 9-1-2022 8 am CST –  our roster normally fills in a couple hours.

Registration for the 2023 Arrowhead Winter Ultra Race will be handled by UltraSignup.  On 9-1-2022 you can find the registration page HERE.

We limit our roster size in order to maintain solitude on the trail and to keep our check points from becoming over crowded. We cannot accept all entries. Preference is given to race veterans and past volunteers. If you were on the 2021 roster you can register as a race veteran.  ALL applications will be added to a wait list and reviewed. You will receive a confirmation from Ultrasignup if your application is accepted. If you don’t get a confirmation in a short time please check your e-mail spam folder. You will not be billed until you confirm acceptance. We will keep a small wait list. We take rookies every year.

You must have a qualifying race before applying.  For bikers, we require at least a 200 mile road bike race or 100 mile off road race, preferably in winter.  We require at least a 100 mile race for foot and ski competitors, preferably in winter.  If you don’t have a qualifying race but feel you have other experience that would allow you to safely complete Arrowhead, please list that on your application.

Pray for cold and snow – we look forward to seeing all the racers, sponsors, and volunteers.

General qualifying requirements listed on application. Keep in mind, this race is unlike any Ultra you likely encounter in lower 48.  You can freeze your tail off if not careful and then we would feel very, very bad and the race likely would not happen next year and we would have to notify your next of kin.

Accepted Entries non-refundable (please don’t ask). We limit the roster to maximize solitude on the trail, we cannot accept all applications. When the roster is full, it is full.  We can’t guarantee race veterans a spot if they apply late.
