If you’ve never been involved with the Seattle Marathon family of events, the 5K Run/Walk is a great introduction! This 3.1 mile race on Saturday, November 24th, is perfect for both runners and walkers. Use it as a warm-up for the Amica Insurance Seattle Marathon and Half Marathon, or create a fun, family outing to burn off some of those Thanksgiving Day calories. Treat your out-of-town guests to stunning views of Seattle while doing something healthy for the entire family. The 5K start is at the Seattle Center near 3rd & Mercer. It’s an out-and-back course that travels through the streets of Downtown and finishes by the International Fountain at Seattle Center. The 5K course USATF certification number is WA 10060MN.
