This is a trail party you won’t want to miss. Right in the heart of beautiful San Marcos, this race is a neighborhood race that feels like the middle of nowhere in the thick of the trail system. It’s an amazing course that will deliver single track trails, rolling hills, rocks, fast sections, and the Tejas Trails spirit.

This race is made possible by the great work of <a href="https://greatspringsproject.org" target="_blank" rel="nofollow noopener noreferrer">Great Springs Project</a>. Don’t know what that is yet? Check out <a href="https://greatspringsproject.org" target="_blank" rel="nofollow noopener noreferrer">this link</a> or just come to the race and learn how the Edwards Aquifer under these trails is critical to sustainable clean water for our growing cities. We are incredibly proud to support their grandiose efforts, alongside the city of San Marcos via this trail race!
While every racer will get some cool swag, September 16 is the deadline to get a shirt.
