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

A Merry Christmas Run 5K/10K/13.1 SEATTLE is run in Seattle, Washington, on December 26, 2026, with all four distances starting together at 7:30 a.m.: the half marathon (13.1 miles), the 10K, the 5K and a family one-mile fun run. Community and celebration come before competition, and timing is a personal choice, made with the running app you prefer or left out altogether. A race shirt, a finisher medal and a gift bag are included.

Late December is when consistency counts for more than any single workout, and an event on the 26th is a good way to protect the habit through a week of interruptions. The 5K and the 10K fit into any plan without adjustment. The half deserves more respect: twelve weeks of steady running with a weekly long run, and a decision to run it at long-run effort rather than as a test. Families can share the one-mile start regardless.
