Winter Trail Series: Seward Solstice Run 4.2mi | 10k

December 21, 2019 @ 8:30 am - 12:00 pm PST

|Recurring Event (See all)

An event every year that begins at 8:30 am on day third of December, repeating until December 17, 2022

The Winter Trail Series celebrates Seattle and the Eastside’s local parks with trail runs that will keep your winter fitness warm. All events have a choice of at least two distances, with shorter course lengths ranging from 4-8 kilometers (2.5-5 miles), and longer course lengths ranging from 10-21 kilometers (6-13 miles). So rally your running pals and put these motivating events on your calendar!

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.

Join us for a 4.2-mile or 10k trail run at Seward Solstice, the fourth event in the Winter Trail Series.

Course Description
The loop route starts out on the wide and smooth main trail, which is flat-to-rolling before dipping downhill toward the tip of the peninsula. Just before the main trail emerges from the forest onto the waterfront promenade, the course takes a left turn onto the smaller trails that climb and traverse the Western side of the peninsula. A few-hundred-meter segment of this return stretch features a twisty-turny section, with several small fallen trees to leap over and some roots and other bumps to negotiate. This will give most runners a breather as they slow down a bit before the trails get wider and straighter again toward the end of the loop.

Aid Station
There will be an aid station adjacent to the start/finish point, so 4.2-mile runners will pass it once during their run, and 10km runners will pass it twice.

Aid stations offer water, electrolyte drink, and some carbohydrate-rich or salty foods, such as cookies, pieces of energy bar, gels, chews, chips, bagel, fruity candy, fig bars, peanut butter and jelly sandwiches, and/or bananas.

8:30am – Check-in and day-of-event registration opens

Directions & Parking
The start/finish will be located close to the second parking lot. When entering the park, pass the first parking lot on your left (near the beach and pottery studio) and continue up the hill on Seward Park Rd. until you see a parking lot on the right.
