Greenlake 5K and Wellness Festival

Greenlake 5K and Wellness Festival runs on October 24, 2026 in Seattle, Washington, with the 5K starting at 8:30 a.m. The event pairs a single 5K with a wellness festival, so the race itself is short and the morning built around it is a large part of the appeal. Green Lake gives the event its name and its setting, and one distance means there is nothing to weigh up on the entry form.

Choosing a 5K in late October is a smart way to test your fitness before winter without needing months of buildup. Four to six weeks of consistent running — three or four easy runs plus one faster session a week — puts most people in shape to run it well. If it is your first race, hold back for the opening half mile; the temptation to go out hard is strongest on a short course.
