Sunrise Marathon 5K/10K/13.1 SAN ANTONIO

Sunrise Marathon 5K/10K/13.1 SAN ANTONIO is run in San Antonio, Texas, on December 12, 2026. All four events, the half marathon (13.1 miles), the 10K, the 5K and a one-mile family fun run, start at 7:30 a.m. on a scenic course timed for sunrise. Timing is optional, and each athlete gets a performance race shirt, a finisher medal and a digital training pack.

Run-walk is a legitimate way to cover any of these distances, not a lesser one. A steady cycle of running minutes and walking minutes, decided before the start and held from the first mile, gets plenty of people through a half marathon feeling better at 12 miles than those who ran the opening three too hard. If you prefer to run it straight through, build to a 10 or 11 mile long run and keep the pace conversational until the halfway point.
