Brooks Lake Sammamish Half Marathon presented by REI

Get ready to lace up and unleash your energy at the Lake Sammamish Half Marathon! Imagine the thrill of sprinting across a seamless blend of pavement and smooth gravel, connecting the scenic Marymoor Park to the refreshing shores of Lake Sammamish State Park. Whether you're aiming to smash your personal best or simply enjoy a rhythmic walk, this flat course is your ticket to an invigorating half marathon experience.

But wait, there's more – as you race against the clock with your custom bib and chip-timing, we sweeten the deal with swag like a participant shirt and a well-earned finisher medal. Stay fueled at well-spaced aid stations, and be greeted at the finish line by a lively mix of food and music by the beach. Do your bit for the planet – it's a cupless event, so bring your bottle or grab a reusable cup from us at the start!

For those who can't make it in person, we've got virtual race spots – conquer the distance at your pace. And if giving back is your jam, seize a charity bib, champion a cause, and potentially have your registration fee waived. Dive into all the details and gear up for an unforgettable race experience!
