The Austin Solstice Circuit Challenge invites runners to chase personal bests at Texas' fastest summer ultramarathon. The event features a well-designed 1.55-mile paved figure-8 loop in the picturesque Pace Bend Park on Lake Travis, ensuring optimal conditions for speed. With an evening start for longer distances, participants will enjoy the setting sun and the Buck Moon while navigating a flat, traffic-free course. Runners can choose from distances including the marathon and 50K, facing minimal elevation changes that promote record-setting performances. Unlike typical summer ultras, this race offers cooling aid stations and favorable terrain, making it a unique opportunity to challenge yourself under the stars. Join for an unforgettable experience as you run through the Texas summer night!
