During the registration process, you have the opportunity to add refund protection offered from Protect Group. This enables you to receive a refund for the race if you are unable to attend the event. Please note: you CANNOT retroactively add refund protection. If you select this option, refunds are given by Protect Group. The race is not involved in the refund process in any way. Refunds will be given on all cart items at the time of your initial checkout (items added at a later date will not be refunded). Please see HERE for approved refund circumstances.


You may transfer your race registration to another individual if you are unable to attend the 2024 race.

The official transfer dates are February 19, 2024 – February 29, 2024. Transfers will close at 11:59 pm PST on February 29, 2024.  We recommend that you transfer your entry to someone you whom have a personal tie. Many people utilize social media which is a great idea, but we suggest using your personal page(s) and stay away from group pages where scammers hover.
