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

New Year's Run 5K/10K/13.1 PHILADELPHIA takes place in Camden, New Jersey, on December 26, 2026, as the Philadelphia edition. Four distances start at 7:30 a.m.: the half marathon (13.1 miles), the 10K, the 5K and a one-mile family fun run. The event is designed for runners who want a challenge and company in equal measure, with your own pace respected and your timed result available through the running app you already use. Entry brings a technical shirt, a finisher medal and a digital training pack.

A half marathon the day after Christmas is not a natural personal-best setting, but it is an excellent way to convert a fall of training into something concrete before the year turns. Run it at long-run effort if you are building toward a spring marathon, or race it if the fall season left you sharp. Twelve weeks with a weekly long run is the base you want either way, and the clubs on site are a reasonable place to find company for the winter miles.
