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

New Year's Run 5K/10K/13.1 SEATTLE runs in Seattle, Washington, on December 26, 2026. The half marathon (13.1 miles), the 10K, the 5K and a one-mile family fun run share a 7:30 a.m. start, and every distance can be run or walked at your own pace. Timing is optional, a virtual entry is offered for anyone who prefers to run from home, and finishers take away a gift bag with a shirt and a medal.

The last week of December is when consistency matters more than sharpness, and a half marathon is a reasonable way to prove you have kept some. Run it as a long run with company rather than a time trial and the week costs you very little. Anyone stepping up to 13.1 for the first time should build for ten to twelve weeks with one long run in each. The 10K is the sensible pick if a spring goal race is already on the calendar.
