Arrowhead Ultra 135
Train Hard - registration for Arrowhead 2025 (Jan 27th to Jan 29th) will open 9-1-24 8 am central time..
The Arrowhead 135 is recognized in the book "The World's Toughest Endurance Challenges" by Richard Hoad and Paul Moore as one of the 50 toughest races in the world. It is a human powered Ultra Marathon taking place in the coldest part of winter in the coldest city in the lower 48 states. Our average finish rate is close to 50%, the finish rate for new racers is much lower. 2019 finish rate was 35%.
The course covers 135 miles across Northern Minnesota on rugged, scenic Arrowhead State Snowmobile Trail from International Falls to Tower, MN Fortune Bay Casino. Pick your mode of transport at start: bicycle, ski or foot. This is our 21st year of Arrowhead Ultra- we attract some of the best winter ultra-athletes in the world.
Arrowhead is historically one of the coldest races anywhere, even the Arctic, check our average temps, virtually every year luck has us -30 to -40C/F, we have frostbite to prove it. Snowstorms are another possibility! Arrowhead 135 is an organization of volunteers dedicated to the promotion of human powered ultra-endurance events across the beautiful Arrowhead Region of Northern Minnesota. Our Race Mission is fostering national and international amateur endurance sports such as winter-biking, skiing and trail running.
Our goal is to offer, fun, educational, yet challenging ultra-endurance event in extreme trail and weather conditions in Northern Minnesota.
Our entry fee is modest and monies left over from race expenses are donated to the Special Operations Warrior Foundation Charity, providing college scholarships to children of US Spec Ops Soldiers killed and wounded, the Falls Food Shelf, and bikes are donated to local kids.
Special Note
We do not normally offer refunds of entry fees. If we have to cancel the race we will refund ~$150 of a racer’s entry fee. The balance will be used to cover fixed costs and donated to race charities.
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.
