2023 Race Registration
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.
SEE YOU IN I-FALLS! AND HOPEFULLY (50% of you) AT FORTUNE BAY!!!
General Notes
The 19th annual AH135 will be Jan 30th to Feb 1st, 2023. Gear check will be Jan 28th/29th.
Completing one of the below accomplishments would typically qualify an entrant for this year’s Arrowhead Winter Ultra; however, entry is not guaranteed. The race directors reserve the right to change the rules in the interest of safety and sportsmanship or for any reason deemed appropriate by the race officials. The race directors reserve the right to select entrants based on other important considerations, as well as due to the requirements of insurers, sponsors, the Minnesota State DNR and other regulatory agencies.
Basically, we look for both endurance and cold weather experience. Below are general guidelines – race veterans and volunteers get preference for entry.
Qualifying activities for runners:
- Completing a prior Arrowhead 135, Tuscobia 160 or similar race.
- Finishing 100 mile foot race or completed multi-sport event, including a 100 mile run. A race in winter conditions improves your odds of being selected and surviving.
Qualifying activities for bikers:
- Complete a prior Arrowhead 135, Tuscobia 160, Susitna, or similar race.
- Finishing 24 hour bike race, with minimum of 100 miles completed for off-road, or 200 miles on road. A race in winter conditions improves your odds of being selected and surviving.
Qualifying activities for skiers:
- Complete a prior Arrowhead 135, Tuscobia 160, or similar race.
- Finishing a 24 hour ski race with a minimum of 100 miles completed.
There are lots of articles, stories, and photo albums from racers, reporters, and volunteers. Go read them all.
