Our normal deferral deadline ended on April 9. You do have another option to get a deferral into our 2019 race, however. If you can fill an open course intersection volunteer position for either the 5K on April 27 or the races on Saturday, April 28, we will defer you into our 2019 race at no charge.

Here’s what you need to do:

1. Sign up for the course intersection job of your choice. Visit to do this.

2. Once you receive the confirmation of your job, print a copy of the confirmation and mail it, along with a completed Deferral Form, to the address listed on the form. You do NOT have to pay the $20 deferral fee. That’s our thank you for volunteering.

3. Doing #1 and #2 guarantees you a complimentary entry into our 2019 race for the event that you weren’t able to run this year. We will contact you with directions for how to get registered once we open registration for 2019 in July.
