Iron Horse Half Marathon

The Iron Horse Half Marathon is a scenic, mostly downhill half marathon held in Washington state, starting at Olallie State Park and finishing in North Bend. The 13.1-mile course follows the Palouse to Cascade Trail and Snoqualmie Valley Trail, both former railroad tracks, offering a gentle elevation loss of about 880 feet. The unpaved route features beautiful river and forest views, with five aid stations providing electrolytes and gels.

The event is USATF certified and has been voted one of the best half marathons in Washington multiple times. It also offers a virtual race option and emphasizes environmental responsibility with cupless racing. Visit the organization's website for the most recent information.
