Registration and Refund Policy

We understand that things come up. If you can no longer run the race, if you let us know more than one month in advance, you will receive 100% race credit for another Blaze Trails Running event. If you let us know between one month and two weeks prior to race day, you will receive 50% race credit towards another Blaze Trails Running event. We will not allow any refunds or transfers less than two weeks before race day. No exceptions.

Bib transfers to another runner are allowed up until the two weeks prior to the race only if the race has not sold out. If you are interested in transferring your bib to another person, please contact us immediately. It is very important for the safety of all runners that we have the correct contact and medical information. If the shirt order has already been placed, the person you transfer to agrees to accept the shirt size that you ordered. A $15 administration fee (plus transaction fee) will be charged to the person who is accepting the bib transfer. We do not allow transfers if the event has sold out and have a wait list. In that case, we will follow the posted refund policy and allow the next person on the wait list to register. We require transfers to be completed no later than two weeks prior to the race. This allows us to keep our focus on producing the event and other important race details during the race week. If you contact us in the last two weeks to ask for a transfer, we will not reply and the transfer is not allowed. No exceptions.

Refund and/or transfer requests must be made in writing by sending an email to info@blazetrails.com. Refunds are only processed as credit to a future event.

I further understand that I am not entitled to a refund if the race director and/or race officials are forced to cancel the race due to any participant safety issue on the course that is out of the race organizer’s control. This may include, but is not limited to flooding, lightning or any other weather condition that makes the course unsafe for participants.
