Lake Sammamish Half Marathon

The Lake Sammamish Half Marathon is a point-to-point race held in early March, running along a paved trail from Marymoor Park in Redmond, Washington, to Lake Sammamish State Park in Issaquah. The 13.1-mile race starts at 7:30 a.m.

Runners receive chip timing, a personalized bib, a participant shirt and a finisher medal. Aid stations offer drinks and energy gels, and the event is cup-free in support of sustainability, so bring a bottle or collapsible cup. There is a walker category with a generous time limit, and a virtual option with limited spots lets participants cover the distance whenever it suits them, with rewards mailed afterward. Early March in the Seattle area is usually cool and damp, so a light rain shell is a sensible companion.
