Lake Sammamish Half Marathon
Overview
Course Description
The first two miles of the race unfolds entirely within Lake Sammamish State Park, along the trails that wind through the park, and then runners head out North Sammamish Road.
From there, the course takes runners east toward the trail, which they enter just after passing by the mile 3 marker. Along the route, the half marathon route features gravel surfaces for most of the course (runners will encounter some paved surfaces near both the beginning and the end of the race).
The trail, which stretches 11 miles from Marymoor Park south to the town of Issaquah, lies in the bed of a former railroad and opened in 2006 as a recreational trail for running, walking and biking.
Though there are some gentle rises in elevation over the course of the 13.1-mile half marathon route, runners can expect a mostly flat course for virtually the entire race, organizers note, as this was a large part of the appeal of the route for the marathon and half marathon.
