Seward Solstice Runs
December 20, 2025 @ 8:30 am - 12:00 pm
Join Northwest Trail Runs for a 4.2-mile or 10k trail run through the 100+ acres of old growth forest at Seward Park.
Situated on a peninsula surrounded by Lake Washington, Seward Park provides perhaps one of the greatest contrasts in Seattle: 100+ acres of old growth forest, just minutes from the city center. The run route follows a loop that is almost entirely in the forest, so there is ample opportunity to enjoy what the Friends of Seward Park fondly call “The Magnificent Forest,” with graceful Western Red Cedar and towering Douglas Fir, along with a lush tapestry of other native plants. You may even hear a Pileated Woodpecker pecking out a nest or rooting for a meal in an old tree trunk.
