Is there a waiting list? Can I get a refund?

We maintain no waiting lists once we sell out. We do not give refunds - the Grizzly Peak Century goes on, rain or shine!

So, if you are unable to make it to the Century, we invite you to give, sell or trade your Grizzly Peak Century entry to someone else. You make the arrangements, but you need to tell us, and all you need is this form. (This gives us the personal information for the replacement rider, and her/his signature on the Release.) You don't need to tell us in advance (but if you send a note to the century registrar, we'll make a note to look for your replacement). There is no charge for the transfer. The transferee just needs to bring the completed form to the Century.
