Iron Horse Half Marathon - North Bend, WA

The Iron Horse Half Marathon is a USATF certified half marathon held on the Snoqualmie Valley Trail near North Bend, Washington. The route follows a former railroad grade and uses a point to point layout that was modified after 2026 flooding into a partly out-and-back course.

The entire course is unpaved and consists of smooth, hard packed dirt and gravel; regular road running shoes are suitable. The race now features a gentle climb in the first few miles followed by a net downhill for the latter portion of the course. There are five aid stations spaced about 2 to 3 miles apart supplying Tailwind electrolytes and GU gels. The event is cupless and participants are expected to bring a handheld bottle or a small reusable cup.

Pacers are provided for a range of target finish times. Free gear check is available with bags transported from the start to the finish. Walkers are welcome. Strollers are allowed but require use of the shuttle to reach the start; parents or guardians must accept responsibility under the stroller policy. Dogs may not participate on the course but are allowed in the start and finish areas.

Awards are given to the top three male, female, and non-binary finishers by gun time, plus age-group awards in five year increments, to be picked up at the Orca tent. The race benefits the REI Cooperative Action Fund.
