The Lake Sammamish Half Marathon takes runners along the smooth gravel 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!
The race is chip-timed, and each racer will receive a custom bib, a finisher medal, a microfiber tech shirt and sponsor products. Aid stations are provided every few miles 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.
This event benefits Cascade Challenge, a non-profit organization dedicated to providing leadership and outdoor adventure opportunities to youth ages 14-20.
