Iron Horse Half Marathon - North Bend

The Iron Horse Half Marathon is a USATF certified half marathon starting at Olallie State Park and finishing in North Bend. The Iron Horse Half Marathon is a point to point half marathon taking place in Washington state on the Iron Horse Trail (part of Washington State Parks) and Snoqualmie Valley Trail (part of the King County Parks system). Both trails are the remains of old railroad tracks, hence the ‘Iron Horse’ moniker. The course is nearly all downhill at a steady, gentle grade, except for some very short flat sections.
