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! For more information See Ahotu Marathons' and Sammamish Patch's articles about the run and check out the Lake Sammamish Half Facebook Page for the latest updates.
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.
This event benefits Cascade Challenge, a non-profit organization dedicated to providing leadership and outdoor adventure opportunities to youth ages 14-20.
Besides this run, we also organize trail runs throughout the year via the Evergreen Trail Runs Series. You can find the full schedule on our website and discussions with other runners on our Facebook Page.
