Great Springs Project (GSP) is hosting the third-annual San Marcos Trail Race in partnership with Tejas Trails. 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. Join GSP and Tejas Trails on October 11th - whether it be by running the race or lending a hand through volunteer support. Great Springs Project is a Texan by Nature Conservation Partner.
