Sleigh that 5k

Sleigh that 5k gathers runners and walkers of every age and ability at Green Lake Park in Seattle, Washington, on December 20, 2026, with the 5K run or walk starting at 10:00 a.m. Festive outfits are part of the appeal, and the event leans on music and holiday spirit to set the tone. The atmosphere is a welcoming one, with plenty of chances to stop for photos along the way.

A 10:00 a.m. start is the most forgiving on the calendar: breakfast, coffee, a proper warm-up and no scramble in the dark. If you are pushing for a time, that extra hour is worth spending on 15 minutes of easy jogging and a few strides. If you are here for the costume, the 3.1 miles will pass quickly enough that a full outfit is more comfortable than it would be over a longer distance.
