about the brooks Lake sammamish half presented by REI
The Brooks Lake Sammamish Half Marathon presented by REI 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 as it is 100% pavement. We offer a generous 4.5 hour time limit for all participants. This flat run is perfect for a half-marathon personal best whether you’re running or walking!
The Lake Sammamish Half was started in 2010 by Roger Michel and Yumay Chang, and in later years Dana Anderson directed the race to great success. Orca Running was thrilled to be chosen to take over the race in 2021.
Orca Running acknowledges that the Lake Sammamish Half Marathon takes place on the Indigenous Land of Coast Salish peoples who have reserved treaty rights to this land, specifically the Snoqualmie Indian Tribe (sdukʷalbixʷ). We thank these caretakers of this land who have lived and continue to live here since time immemorial.

RUNNER VIEWPOINTS
The majority of the course is accessible via private driveways. To respect the residents who reside along the trail we ask that your friends and / or family use the recommended runner viewpoints:
AWARDS
Overall awards will be given to the top 3 men, women, and non-binary runners based off of gun time not chip time. So, you should start in the front of the pack. We also give out age group awards in 5 year increments, so be sure to check your results at the Orca Running tent. We DO NOT MAIL OUT AWARDS after the race, they must be picked up at the race.
PARKING
Start Line Parking: There is street parking around Redmond City Hall in downtown Redmond, and in the parking garage at the Redmond Senior Center. This parking garage will fill quickly. There is also parking at Redmond Town Center (if you are going to feast or drink afterwards), it is about a 15 minute walk away. There is NO parking at the Redmond Library. Plan ahead and arrive early. We recommend using transit, or being dropped off.
Finish Line Parking: There is NO parking at the finish line. Your friends and family are welcome to park at Lake Sammamish State Park. However, because it’s a state park, every vehicle is required to display a Discover Pass (good at all state parks and other state lands). You can purchase a pass in advance online or at the park’s automated pay station. Both one-day and annual passes are available. The parking at Lake Sammamish State Park is about a half mile/15 minute walk from the new finish line.
*If not parking at Lake Sammamish State Park please be careful to pay attention to no parking signs as you may be towed.
LODGING
We recommend the Seattle Marriott Redmond or Hyatt House Redmond.
GEAR CHECK
Free gear check is available at the Lake Sammamish Half. In an effort to reduce waste, we will not be providing drop bags, so PLEASE BRING YOUR OWN BAG and the more identifiable/colorful it is the easier it is for our volunteers to find! We will have identification tags for you to use. Drop bags will be available to pick up at the finish line.
POLICIES
We have a clear set of policies that we uniformly follow for all races. Entries are not refundable, but you can defer your entry, transfer it to another race, or transfer it to another participant. You can review our full set of policies here.
CUPLESS RACING
Orca Running is committed to reducing waste and protecting the environment. As part of this commitment, we are making all events cupless. The tiny little cups that are used for an instant generate tremendous amounts of garbage. We recommend you purchase a handheld bottle, a hydration pack, or we can provide you with a small re-useable cup that folds easily into your waistband to use during the entire race and future races.
CHARITY PARTNER
Time outside and connection to nature is fundamental to the health and well-being of all people. But millions of Americans lack access to the outdoors, and far too many people do not feel a sense of belonging or safety outside.
That’s why REI founded the REI Cooperative Action Fund. It directly supports organizations working to improve the health and well-being of people and communities through time spent outside. Thanks to REI Co-op’s generous support, 100% of your gift goes to grantee partners.
