St. Paddy's Day Lucky Run 5K/10K/13.1 SEATTLE

St. Paddy's Day Lucky Run Seattle takes place in Seattle, Washington, on March 20, 2027, with a 7:30 a.m. start for all four distances: the 13.1-mile half marathon, a 10K, a 5K and a one-mile family fun run, run under the St. Patrick's theme shared across the series.

A late-March date makes this a natural finish line for a winter of consistent training, and the 10K is the honest way to measure what those months were worth. The half asks for more structure, roughly twelve weeks with a weekly long run and one session at threshold effort, and it pays to rehearse race-morning logistics in advance when the gun goes at 7:30. Shorter entries let newer runners test the waters without a training plan.
