New Year's Run 5K/10K/13.1 PHOENIX

New Year's Run 5K/10K/13.1 PHOENIX is run in Phoenix, Arizona, on December 26, 2026, with a half marathon (13.1 miles), a 10K, a 5K and a one-mile family fun run all starting at 7:30 a.m. The event puts a challenge and a sociable field in the same morning, leaves you free to hold your own pace, and lets you follow your timed result through your usual running app. A technical race shirt, a finisher medal and a digital training pack are part of the entry.

If next year involves a spring half or marathon, this is a sensible place to start it: a supported long effort in company beats a solo run on the same date, and the field gives you something to sit behind when your pace starts to drift. Twelve weeks with one long run a week covers the half; the 10K asks for less and still tells you something. Local clubs are present, which makes the finish area worth lingering in.
