About the Event

Challenge the rugged, rocky terrain of Eisenhower Park in San Antonio at the Alamo City Ultra on Saturday, February 7, 2026, a versatile event offering 50K, 25K, 10K, and 5K distances on a demanding one-mile loop. With a substantial 425 feet of elevation gain per circuit, this course delivers a relentless mix of natural trails, roots, and technical footing, testing runners and ruckers across a format that is both simple and brutally effective. Choose your distance with staggered start times, from the 50K's dawn start to the later 5K, and embrace the supportive, loop-based camaraderie where full aid stations and outstanding volunteer support await at every pass. Every participant is rewarded with custom swag, a finisher medal, and the distinct satisfaction of conquering one of Texas' most deceptively tough short courses.

With a 12-hour overall cutoff and a hard final loop deadline of 4:45 PM, the event encourages strategic pacing and pure grit against the clock and the challenging terrain. Whether you're aiming for an ultra-distance personal best or seeking a robust introduction to trail running, this Rise Racing Co. event provides a premium, chip-timed experience with free race photos. Secure your spot to test your limits on this classic San Antonio course, where the community spirit is as strong as the limestone underfoot.
