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.

The race is chip-timed, and each racer will receive a custom bib, a finisher medal, a long-sleeve microfiber Tech Shirt and sponsor products. 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.
