January 28 - January 30
The 15th annual AH135 will be Jan 28th to 30th, 2019.
Registration for the 2019 Arrowhead Winter Ultra Race will be handled by UltraSignup. You can find the registration page HERE.
Please note that registrations will be done lottery style due to limited space on our rosters. Race veterans are encouraged to apply 9-1-18 and race rookies are encouraged to apply 10-1-18. Roster decisions will be made after those dates. We strive for ~2/3 vets and ~1/3 rookies. You will not be charged until you are added to the roster.
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.
