Course Map: Iron Horse Half Marathon


Runners follow a point-to-point route that’s almost all downhill at the Iron Horse Half Marathon, which starts in Olallie State Park and finishes in North Bend, at Claggett Field. In between the start and the finish line, organizers point out that 90 percent of the course is downhill as it makes its way first along the Iron Horse Trail and then along the Snoqualmie Valley Trail, after the turnaround at Rattlesnake Lake.
