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

A Merry Christmas Run 5K/10K/13.1 SAN FRANCISCO takes place in San Francisco, California, on December 26, 2026. The half marathon (13.1 miles), the 10K, the 5K and a family one-mile fun run all start at 7:30 a.m. The event is framed around community and a festive morning rather than results, with timing left to your own app or dropped entirely. Every entrant receives a race shirt, a finisher medal and a gift bag.

Set your expectations by effort rather than by a personal best, because the value of a race like this is the company and the excuse to run on December 26. That framing suits a half used as a long run inside a spring build, and it suits a first 13.1 attempt just as well, provided twelve weeks of consistent running sit behind it. The 5K and the one-mile run make it possible to bring people who would otherwise be spectators.
