Mark your calendars for September 7, 2024, as we invite you to join us for a fun-filled trail run near Austin and San Antonio, right by the lake! This event promises to be a fantastic gathering for friends and family, combining the thrill of a trail run with the refreshing waters of the lake for a post-race party like no other.

As you cross the finish line arch, you’ll find yourself right at the water’s edge, where you can plunge into the lake to cool off and kickstart your floating post-race celebration. Embrace the laid-back vibe of the event, where the distance may vary slightly each year depending on the lake’s water levels, adding a touch of unpredictability to the experience – and that’s just perfect when everyone is in a mellow mood.

Every participant will receive some awesome swag, but be sure to register by August 13 to secure your event shirt. Additionally, during registration, there’s a $10 fee for a one-day access pass to the park. If you plan to stay for more than one day, additional fees will apply upon entering the park.

So grab your running shoes, gather your loved ones, and join us for a memorable day of trail running and lakeside fun. Whether you’re a seasoned trail runner or a first-timer, this event promises excitement, camaraderie, and plenty of opportunities to soak up the natural beauty of the surroundings.
