From the organizer

The Brooks Lake Sammamish Half Marathon presented by REI is a point to point race from Redmond to Sammamish. You will run along the East Lake Sammamish Trail that is fully paved. We also offer a half-marathon walk category with a generous 4 hour time limit. This flat run is perfect for a half-marathon personal best whether you’re running or walking!

The race is chip-timed, and each participant will receive a chip-timed bib, participant shirt, and a finisher medal. Aid stations are provided every few miles (see course map).

The Lake Sammamish Half is cupless, so you either need to bring a handheld bottle, wear a hydration pack, or we can provide you with a re-useable cup at the start line.

VIRTUAL RACE INFO - We have 30 spots for virtual runners. Once they sell out there are no more available. You can run the distance all at once or break it up into chunks and run it on the date of your choosing. You will receive a shirt and medal that will be mailed after the in person race.
