Runners start the out-and-back course for the Beat the Blerch Half Marathon at Tort-MacDonald Park on 40th Street, near the confluence of the Snoqualmie and Tolt Rivers. From there, the race heads south through the park and then onto the Snoqualmie Valley Trail, which they’ll stay on all the way until they reach the half-way point of the race. After that, they’ll run the same route in reverse, all the way back to the park for the race finish.
Note: The course map above provides the approximate route for the race. Though every effort has been made to ensure its accuracy, changes are sometimes made to race routes due to weather conditions, road closures or other circumstances that can require a course to be changed.
