Austin Solstice Circuit: Marathon, 52M, 50K, 25K, 10K, 5K

Embark on an extraordinary summer running challenge at the Austin Solstice Circuit, set for July 25-26, 2026, at the picturesque Pace Bend Park on Lake Travis in Spicewood, TX. This event lives up to its reputation as the "fastest summer ultramarathon in Texas," offering distances for every ambition: 5K, 10K, 25K, Marathon (USATF certified), 50K (31 miles), and an epic 52.7-mile ultra. What truly sets this race apart is its strategic evening start times for longer distances, allowing runners to experience the cooler temperatures of a Texas summer night, racing from sunset to stars under the glow of July's magnificent Buck Moon. For shorter distances, both evening and morning start options are available, ensuring a unique experience for all participants. Typical race day conditions in late July see highs around 96°F and lows around 73°F, with a minimal 6% chance of precipitation, making the evening format particularly appealing.

The Austin Solstice Circuit features a perfectly engineered 1.64-mile paved figure-8 loop course, meticulously designed for speed and personal bests. With a minimal elevation gain of just 33 feet per loop, runners will find the terrain gentle and predictable, providing ideal conditions for consistent pacing. The scenic route winds through the breathtaking Texas Hill Country, offering stunning views of Lake Travis, majestic oak trees, and dramatic limestone bluffs, providing a beautiful backdrop for your challenge.

Runners will benefit from a fully stocked aid station located at the start/finish hub, accessible with every 1.64-mile loop, meaning constant support and no need to carry excessive supplies. The loop design also facilitates easy crew access for personalized support, a feature especially appreciated by first-time marathoners and ultra-runners. Personal pacers are welcome for marathon, 50K, and 52.7-mile solo events after a certain number of loops. All finishers receive custom-designed medals and challenge coins, part of the Race Austin Series, with overall winners vying for substantial cash awards. Whether you're chasing a PR, a Boston qualifying time, or the thrill of a night ultra, the Austin Solstice Circuit promises an unforgettable journey.
