Runners start and finish the out-and-back course for the half marathon at Eagle’s Crest inside Eagle Creek Park, and from there head out onto a U-shaped route that takes them over the Eagle Creek Reservoir to the other side of the lake. The course features a few road stretches, but most of it is made up of single-track trails, old dirt park roads and double-track trails.
