2021 Frost Eagle Trail Run


5-mile & Half Marathon

Saturday, January 23, 8:00am-11:00am starts

Soaring Eagle Regional Park, Sammamish, WA

A sanctuary for birds, deer, bobcats, and black bear, Soaring Eagle Regional Park is also a quiet sanctuary for humans. Six hundred acres of forest and wetlands interrupt miles of suburban homes on the edge of the flat Sammamish Plateau and are host to 12 miles of trail that walkers, runners, mountain bikers, and equestrians enjoy.

The trails at Soaring Eagle are arranged like a spider’s web, with the wide Pipeline Trail cutting through the center and a network of interconnected trails radiating out from it. The surrounding trails were designed with little deference to the landscape, meaning that they twist, turn, swoop, and dive over all the little bumps in the park. With no major climb, you may find yourself hooting and hollering over these miniature roller coasters and begin thinking of the word “hill” in a whole new way. There is also a healthy population of rocks and roots on the trails, so there will be little time for zoning out as you dab through nature’s hopscotch.

Join us for a 5-mile or Half Marathon at Frost Eagle, the sixth 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 2020-21 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
