Registration and Refund Policy
We understand that things come up. If you can no longer run the race, if you cancel more than 30 days in advance, you will receive 100% race credit for another Blaze Trails Running event. If you cancel between 30 days 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.
To cancel, log into Ultrasignup > Registration History and select “Edit” to cancel your race. Your credit needs to be used within one year. If you need an extended time to use your credit due to medical reasons (including pregnancy) or military deployments, please reach out ahead of time.
Bib transfers to another runner are allowed up until the two weeks prior to the race only if the race has not sold out and there is no waitlist. If you are interested in transferring your bib to a friend, 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, your friend 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 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.
When you register, you acknowledge that we do not provide a refund if we are forced to cancel the race due to unforeseen circumstances that risk the safety of our participants due to conditions that are out of the race director’s control. This may include, but is not limited to flooding, lightning or any other weather condition that makes the course unsafe for participants.
