Iron Horse Half Marathon

The Iron Horse Half Marathon is a scenic, USATF-certified downhill half marathon held in Washington state, starting at Olallie State Park and finishing at Meadowbrook Farm in North Bend. Covering 13.1 miles along the Palouse to Cascade and Snoqualmie Valley Trails—both former railroad tracks—the course features a gentle, steady descent with about 880 feet of elevation loss, mostly on hard-packed dirt trails suitable for regular running shoes. The event offers five aid stations, pacers for various finish times, and a cupless race format to reduce waste.

Recognized multiple times as Washington’s best half marathon, it provides a beautiful, fast course ideal for personal records. A virtual race option is also available. Visit the organization's website for the most recent information.
