Get your friends and family, and join in on this close to Austin and San Antonio lake party and trail run! The finish line arch will be as close to the edge of Lake Travis as we can get it (Austin area’s famed lake boasting over 9 miles of shoreline)! So when you finish you can cruise straight into the water to cool off and start your floating post-race party! This means, as the lake rises and falls each year, the distance will possibly slightly change, so we'll add "ish" to each distance...and that's perfect when everything and everyone stays mellow.
We’re incredibly thankful for the support of this race by the Travis County Parks Foundation!
While every racer will get some cool swag, August 18 is the deadline to get a shirt.
During registration, we are collecting $10 for one day of access to the park. If runners are staying for more than one day, they will have to pay additional amounts upon entering the park.
