The Lake Sammamish Half Marathon 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; about 30% of the course will be on smooth gravel surface and 70% on pavement. 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! We will be taking covid precautions for all participants, volunteers and staff including small. spaced out start waves.
The race is chip-timed, and each racer will receive a custom bib, participant shirt, and a finisher medal. Aid stations are provided every few miles (see course map) with Clif gels/bloks, fruit, nuun and water, and the finish line will be by the beach and includes a nice line up of food and music.
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.
Register for the Virtual Run and you can run your race anywhere the weekend of March 6th-7th. We will mail you your bib, race shirt, and medal!
