Seward Solstice Run
Seward Solstice Run takes place on Saturday, December 19, 2026 at Seward Park in Seattle, WA. The event offers the following race distances:
- 4.2 mile trail loop
- 10k trail loop
The course follows a loop that is almost entirely in old growth forest. The route begins on a wide, smooth main trail that is generally flat to rolling before dipping downhill toward the tip of the peninsula. Before the main trail reaches the waterfront, the course turns onto smaller trails on the western side of the peninsula. A short twisty section on the return features small fallen trees, roots, and other bumps before the trail widens and straightens again. Seward Park’s forest includes Western Red Cedar and Douglas Fir and supports native wildlife such as Pileated Woodpeckers.
An aid station is located adjacent to the start and finish area; 4.2 mile runners pass it once and 10k runners pass it twice. Aid offerings include water, Skratch Labs electrolyte drink, and a variety of carbohydrate rich or salty snacks such as cookies, energy bars, gels, chips, and bananas.
This race is the fourth event in the 2026-27 Winter Trail Series. Participants who complete four or more series events earn custom series swag, and series standings use each runner’s best four performances with points awarded in Female and Open categories.
The event includes a costume contest with a solstice theme called Glitter, Glamour, and the Galaxy, with separate individual and group categories. Visit the organization's website for the most recent information.
