Alamo City Ultra - San Antonio

Alamo City Ultra - San Antonio runs on January 23, 2027, in San Antonio, Texas, and stacks four distances into one morning. The 50K (31 miles) leads off at 6:45 a.m., the 25K (15.5 miles) follows at 7:15 a.m., the 10K starts at 8 a.m. and the 5K closes the schedule at 8:30 a.m. The staggered starts mean runners on every distance are on course at the same time.

An event like this is useful when a group wants one destination and four different goals. The 50K is a genuine ultra and asks for months of patient volume, back-to-back long runs on the weekend, and a rehearsed fueling plan you have actually tested at effort. The 25K sits within reach of anyone comfortable at half marathon distance, while the 10K and 5K make good openers for a spring season. A late-January date in South Texas keeps the winter build honest.
