About the event
The Austin Solstice Circuit Challenge 50K, scheduled for July 12, 2025, challenges runners to test their endurance over 20 loops of a 1.55-mile paved course. Unlike trail ultras, this flat, predictable surface eliminates technical obstacles, allowing runners to focus purely on distance, pacing, and fueling. Hosted by Fit Foundation, this race provides frequent hydration stations and a supportive atmosphere, making it ideal for those chasing a first ultra finish or aiming for a competitive 50K time. Whether you’re tackling your longest race yet or refining your ultra strategy, this event offers a fast, focused test of endurance.
