RACE DAY is Sunday, August 9, 2015.

Online registration will close Friday, August 8 at Noon pending the race doesn’t fill to capacity beforehand.  After this time, you may try to sign up in person at one of the scheduled race packet pickups, depending on if there are any openings.

Race day registration will be available in person at any of the scheduled race packet pickups, and morning of race. Race day registration can be made with cash or check only.

Registration changes, deferral requests, or other edits will not be accepted via email after Friday, August 1 .  Edits such as changing categories, updating information such as date of birth, etc., can be made in person after August 1 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 August 1, 2015,  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 is 8:00 AM
