USATF Certified Half Marathon
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 race for 2021 and beyond.

Save a Tee Plant a Tree
Trees not Tees help events reduce their environmental impact with one simple strategy – offering participants the choice of turning down a free race tee and planting a tree instead.
Orca Running is partnering with Trees not Tees to help reduce the huge number of unwanted and unworn finisher’s tees produced each year and destined to become landfill.
After the event, participants who selected the option to have a tree planted receive a photo and GPS coordinates of their tree’s location.
Packet Pickup/Race Day: $100
Please note that all registrations are non-refundable. Be sure to review our race policies.
Prices do not include processing fees. Online pre-registration closes the day before the race at 8:00pm.

For 2021 shuttles will run at 1/3 capacity and all covid-19 protocols must be followed. Particpants must wear a mask and be spaced out.
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!
After the race plaques will be mailed to the top 3 overall men and women.
Start Line Parking: There is plenty of parking at Marymoor Park. Please arrive early enough to find a spot, pick up your race packet, and get ready to start. Parking costs $1 and can be paid via credit card or cash at the kiosk.
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.
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.
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.

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.
Due to COVID-19 race bibs will be mailed out the week before the race.
You can pick up your shirt and any additional items purchased at the finish line.
The race will start in waves of 10 participants leaving every 3 minutes. Per WA State guidelines participants will be assigned waves according to their estimated finish time.
