Please review the race rules before signing up!! Contact us regarding the 150-mile (160 miles this year) event if you do not have previous long distance winter experience. This is a serious requirement. We understand that a lot of interested participants have completed multiple endurance events (100 k/mile runs/rides etc.) but unless it’s in the dead of winter, we don’t consider it to be sufficient qualification for the 150-mile event. We will revoke your entry if we don’t think you are capable of safely completing the distance.
