about the Lake sammamish half

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 offer a generous 4 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 is thrilled to be producing this season opener.

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.

Shuttles

We provide free shuttles for participants from the finish line back to the start line area. The shuttle is free for all participants.  The shuttles leave when full or every 15 minutes, whichever occures first.  The shuttles are heated.

Don’t forget to pick up your gear check bag before you board the shuttle!

Runner Viewpoints

The majority of the course is accessible via private driveways. To respect the residents who reside along the trail we ask that friends and/or family use the recommended runner viewpoints:

Sammamish Landing Park – mile 3.4

Inglewood Parking – mile 5.5

Lake Sammamish Boat Ramp – mile 10.6

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 parking around the start line in downtown Redmond, and also in the parking garages at Redmond Town Center. Plan ahead and arrive early.

Finish Line Parking: Your friends and family are welcome to park at Lake Sammamish State Park to watch you cross the finish line. 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. 

Traffic to enter and exit the park during the race gets VERY backed up. We have secured use of the parking business parks parking lots across the street from the entrance to the park located at the Lake Place Office Complex. You are not required to have a Discover Pass if you park in these lots, and the walk to the finish line is about .4 miles.

*If you have loved ones coming to see you finish who want to park at the start park please have them arrive at the state park BEFORE 8:45am, and understand that trying to leave the park before 11:00am will be slow going.  

Lodging

We recommend the Seattle Marriott 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. We will have identification tags for you to use. Drop bags will be available to pick up at the race finish at Lake Sammamish State Park.

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.
