The Iron Horse Half Marathon is a point to point half marathon taking place in Washington state on the Palouse to Cascade 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, along with some flat sections

The course for the Iron Horse Half Marathon is pretty awesome. It starts at Olallie State Park and finishes in North Bend at Meadowbrook Farm, and in between the two covers 13.1 miles of beautiful scenery, a couple of railroad trestles, and a whole lot of gentle elevation loss. Please see below for detailed course information, as well as a map of the course. There is an elevation loss of approximately 880 feet. The course starts at about 1300′ and finishes at about 400′ in North Bend. The entirety of the course is unpaved and consists of hard packed dirt. Regular road running shoes work great.
There are a total of 5 aid stations along the course with Tailwind electrolytes and GU gels. Because it is summertime, we strongly recommend that all runners bring extra water and/or an extra bottle with them, in the case of hot temperatures (which are not uncommon in August) to help prevent dehydration. Aid stations are 2-3 miles apart.
Pacers are being provided by Seattle Greenlake Running Group for the following finishing times: 1:30, 1:40, 1:50, 2:00, 2:10 and 2:20.
