Seward Solstice Run


4.2mi & 10k

Saturday, December 19, 9:30am

Seward Park, Seattle, WA

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.

Are you competitive?

  • Your best 4 performances in the Winter Trail Series will rank you in the series standings!
  • If you want to do fewer events, that’s okay! Series events are open to everyone.
  • You may register for events individually, or use Series Registration (link coming) to sign up for more than one event at once for your own convenience. Using Series Registration is not required to be part of the series competition.
  • If you complete any of the 2019-20 season Winter Trail Series events, you are automatically entered.
  • Points will be awarded to women and men separately (both the fastest man and woman will earn 100 points). After receiving points for placement within the women’s and men’s category, participants will then be divided into their age category for the series competition. (You may be the fastest in your category without scoring 100 points, if you are not the overall women’s or men’s winner).
  • The series rewards those with the most points, regardless of what distances they ran.
  • The 1st place woman and 1st place man in each event score 100 points, 2nd place scores 95, 3rd scores 92, 4th scores 90, 5th 89 and so on. Places 64th and lower score 30 points.
  • In the event of a tie, each runner’s highest point score is used for the tie-breaker. If two runners have identical highest point scores, then the next highest point scores are compared until the tie is broken.
  • The top series participants receive special recognition and free entry to a future trail run to be announced.
  • Awards will be presented in the following categories: Open Women, Open Men, Masters Women 40+, Masters Men 40+, Youth Girls 12/under, Youth Boys 12/under, Junior Girls 13-18, Junior Boys 13-18
