Within Sammamish city limits, Soaring Eagle Regional Park offers runners a twisty course that will keep those looking for a more technical course on their toes and offers a nice introduction to the world of bumps and roots to new trail runners. The course, which is mostly single track, but also a small section of wide trail, brings runners through a mature forest and sanctuary wetlands.
There are five course options for this event:
5 Mile (5.1 miles), with 480 feet of elevation gain*
10 Mile, with 1140 feet of elevation gain*
Half Marathon (13.1 miles), with 1460 feet of elevation gain*
20 Mile, with 2280 feet of elevation gain*
50k (31.2 mile), 3460 feet of elevation gain*
All courses start and finish adjacent to the main parking lot. The routes have rolling hills that are mostly short or moderate in grade, and none of the courses are very hilly by trail running standards.
* Distances were measured using a bicycle odometer, and climb was measured using the altimeter function of a Polar watch. Because of noise in the altimeter measurements, climb is likely a bit less than advertised.
