If you wish to withdraw your entry, you must notify us by phone call and email. With the time given with putting this race together, you will receive a refund not to exceed 25% of your registration fee if its before August 24th. Thoughtful consideration goes into this policy. As athletes we do understand injury and life circumstances and how they influence, sometimes negatively, our best laid plans. However, the costs of the event do not subside or change significantly with a withdrawal. Because of the enormous costs associated with the production of an event of the Triathlon we are unable to grant refunds.

We do appreciate your understanding, look forward to your participation in the event, and hope that you give the same thoughtful consideration of the event before signing up.
