Besides the Lake Sammamish Half Marathon, we also organize a series of fun trail run/walk events at various parks in Washington through the Evergreen Trail Run Series. Our goal with the trail run series is to show you some of the most beautiful trails in Washington while keeping it green. We use reusable materials where possible (clip on streamers, reusable cups/plates/cutlery, etc.) and we recycle and compost at every race. We have been doing this for many years, before being green was popular, because we truly believe it is the only way to sustain nature.
Our trail run courses feature a mix of short and long distances, starting from 5K all the way up to 50 Miles. Having a variety of course options gives you the opportunity to progress towards longer distances if you like, or have the whole family join in a run even when everyone's "ideal" running distances are different. Like the Lake Sammamish Half Marathon, Evergreen Trail Runs is a production of 4th Dimension Racing. Besides runs, 4th Dimension Racing also host Mountain Bike Races through the NW Epic Mountain Bike Series, a point series that range in distance from 30 to 100 miles of cross country riding. We are outdoor people at heart, and our race repertoire is constantly expanding and so are the locations we explore.
