RACE DAY is Saturday, July 31, 2016.

We anticipate a sold-out field for the Olympic Distance race, so sign up early!

Registration changes, deferral requests, or other edits will not be accepted via email after Friday, July 22.  Edits such as changing categories, updating information such as date of birth, etc., can be made in person after July 22 at one of the three scheduled race packet pickups.

We strive to provide everyone their requested t-shirt size, but they are ordered weeks in advance.  If you register after July 22, 2016,  we cannot guarantee your requested size will be available on race day. After packet pickup closes on race morning, you can try to exchange your shirt for a different size with what is leftover.  Thank you for understanding.

Unfortunately, we do not provide refunds.

Race Start times and Packet Pickups will be announced when we finalize the course.
