Magnuson Series – Earth Day Run Half Marathon 10K & 5K

Part of a series of running and walking events that take place throughout the summer and fall seasons in Seattle’s Magnuson Park, which lies right on the shores of Lake Washington, the Magnuson Series Earth Day race features five race distances — a half marathon, 10K, 5K and a dash run for kids. The April Earth Day race is one of a dozen planned races in the series, which takes place once each month from January through November, all of which will follow the same race routes around the winding park roads and trails inside Magnuson Park, to give runners a chance to gauge the progress of their improvement in their fitness levels over the course of the second half of the year. Organized by Club Northwest, a locally based running club, the events all use the same 5-kilometer course as the baseline route from which all the other events are built upon. Those running the 5K on the day of the race, for example, run the route a single time, while those running the 10K run it twice, those running the 15k run it three times, and those running the half marathon make three loops around the course, plus an additional one-kilometer stretch near the start & finish line area.
