San Marcos' trail race on the beautiful Purgatory Trails cared for by the San Marcos Greenbelt Alliance! This is a USATF sanctioned event.
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.
Walkers and hikers are encouraged to participate in the 10 mile race.
Runners and walkers will receive a t-shirt. Registrations taken after 10/15/15 may not be guaranteed a t-shirt. Late registrations are not guaranteed a t-shirt.
No dogs allowed. No refunds.
