2026 Lake Sammamish Half Marathon Event Details

The 2026 Brooks Lake Sammamish Half Marathon starts are Redmond’s City Hall and takes runners along the smooth trail that connects Marymoor Park in Redmond to Lake Sammamish State Park in Issaquah. This interurban trail is very popular with runners as it is 100% pavement. We offer a generous 4 hour time limit for all participants. This flat run is perfect for a half-marathon personal best whether you’re running or walking!

 

The Lake Sammamish Half was started in 2010 by Roger Michel and Yumay Chang, and in later years Dana Anderson directed the race to great success. Orca Running was thrilled to be chosen to take over the race in 2021.
