From the Organizer
Join Headwaters, the Rappahannock County Public Education Foundation, for a morning of fun, wellness, and community! Our 5K course offers a great way to support the students and teachers of Rappahannock County Public Schools (RCPS), with all registration fees going directly to benefit RCPS.
We won't be using official timing, so you're free to run, walk, or dash at your own pace! Gather your friends and family, and remember to dress up in your best costume or fall attire for a chance to win a prize!
