Cancellations and Transfers

We understand that injuries happen, you got sick or life was just too chaotic to train for one of our events. No refunds will be issued, however you may transfer your entry to another racer in the same event without penalty until April 15, 2019. You are responsible for finding a person interested in buying your entry, as well as working out payment with that person. Entries do not transfer to other events nor do they transfer year to year. If you would like to sell your entry to another racer, please contact lisa@mountaingoatadventures.com with the name and email of the person you wish to transfer your entry to.

No refunds will be given in the event of an act of God that requires cancellation of the race for the saftey of participants. Once the race has started, no refunds will be given due to delayed start or early conclusion of the race.
