The 10 mile course leads runners through a rather porous section of the Edwards Aquifer. Juniper groves, meadows, ephemeral wetlands, and oak mottes co-exist in Purgatory Creek Greenspace.  More experienced trail runners will enjoy some difficult technical sections of trail during the race while still runnable.

We strive to be a "sustainable" race operation, this means we are a cupless race.  We have water at our water stops but each runner will need to carry a bottle on the course with them.  This is not new for us, lets all up our game and keep trash out of our landfills.

The 5K course is a rigorous course with a medium technical rating and is the perfect introduction into trail running.

Walkers and hikers are encouraged and welcome to participate in the 5K and the 10 mile race.


This race will benefit the San Marcos High School Cross Country

Booster Club.  Go Rattlers!  

Runners and walkers will receive a t-shirt.  Be advised, the tshirts are unisex sizing.

Registrations taken after 12/28/18 are not be guaranteed a t-shirt.  Late registrations are not guaranteed a t-shirt.

No dogs allowed.   No refunds.
