A Merry Christmas Run 5K/10K/13.1 SAN ANTONIO

A Merry Christmas Run 5K/10K/13.1 SAN ANTONIO is held in San Antonio, Texas, on December 26, 2026, with a half marathon (13.1 miles), a 10K, a 5K and a family one-mile fun run, all starting at 7:30 a.m. The emphasis falls on camaraderie and a festive course rather than on racing, and timing is left in your hands, through a running app or not at all. A race shirt, a finisher medal and a gift bag come with entry.

The half is the only distance here that needs planning; the rest can be entered on a week's notice. If you want 13.1 miles to be a good experience rather than a long lesson, arrive with twelve weeks of steady running and one weekly long run of at least ten miles. Runners already deep in a marathon block should hold back and treat it as a paced long run. Everyone else can turn up, run the 5K and be finished before the morning has properly started.
