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.

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: $105

Please note the new information on bib pickup below under ‘Packet Pickup’.
We have partnered with Wander Project to help you do more at Lake Sammamish Half! We are bringing charity bibs to the 2023 event to help you turn your passion into purpose. How does a charity bib work?
A charity bib is a free entry into Lake Sammamish Half in exchange for helping raise awareness and funds for an organization of YOUR choice. You can choose what charity you want to support:
- A US-based 501c(3) that’s near and dear to you
- One of the non-profits associated with the Lake Sammamish Half
- One of the non-profits doing amazing work that’s already working with Wander Project: The Wilderness Society, Challenged Athletes Foundation, Rising Hearts, Team Semper Fi & America’s Fund, and Bigger Than The Trail.
However, if you have a cause in your local community that inspires you to do more, you can choose them as the organization you are raising funds for right at registration!
Once you register for a charity bib, you will be automatically prompted to set up a fundraising page through Wander Project’s peer-to-peer fundraising platform. From here, Wander Project will give you a whole host of tools and resources (including meet-ups, one on ones, templates, and more) to engage your friends and family throughout your fundraising journey. This means you’ll have support from Wander Project at every step of your fundraising process as you raise funds for your selected charity!
The fundraising minimum commitment is $1,000. The percentage of the funds that will be allocated to the nonprofit of your choice depends on the partnership agreement we have with each organization and spans from 65-80% of the net total raised.
By signing up for a charity bib, you are making a serious commitment to raise the amount you agreed to. If you are not able to meet the minimum fundraising amount by the week of the race, you will be required to pay the difference. All donations are final.
Once you raise your minimum commitment, you will be completely registered for the event of your choice. We look forward to seeing you at the Lake Sammamish Half! Let’s turn our passions into purpose and make a difference in the world! Still have a question about how this works?

PACERS! Seattle Green Lake Running Group is providing pacers for the following finish times: 1:30, 1:40, 1:50, 2:00, 2:15, 2:30
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!
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.
Start Line Parking: There is parking around the start line in downtown Redmond, and also in the parking garages at Redmond Town Center.
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.
We ask that if you have loved ones coming to see you finish to please have them arrive at the state park before 8:45am. Traffic to enter the park after this time gets VERY backed up.
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.
To pick up your race packet, you have three options:
- Opt to have your race bib mailed to you. This costs $3.00 and can be selected during the registration process.
- Pick up your bib on race morning. Please consult the schedule below for times and plan on long lines.
- Pick up your bib pre-race at REI Bellevue on Thursday, March 2nd between 2pm-6pm.
