A Merry Christmas Run 5K/10K/13.1 PHOENIX

A Merry Christmas Run 5K/10K/13.1 PHOENIX takes place in Phoenix, Arizona, on December 26, 2026, with the half marathon (13.1 miles), the 10K, the 5K and a family one-mile fun run all starting at 7:30 a.m. Competition takes a back seat to a festive, communal morning, and timing is voluntary, done through your own app or not at all. Every entry comes with a race shirt, a finisher medal and a gift bag.

Without an official result, the way to get value from the half is to decide in advance what it is for. As a supported long run inside a marathon build it is close to ideal, held at an effort you could sustain in conversation. As a first attempt at 13.1 miles it needs a twelve-week runway with one long run each week. As an all-out effort it is the wrong distance here, and the 5K, short enough to race by feel, is the better tool.
