Environmentally Responsible Racing

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.

The course

The Fly 5K course is a modified out-and-back course that starts and finishes at the Aviation Pavilion, on the west side of East Marginal Way. Participants will run past the main Museum of Flight building as well for fantastic views of iconic aircraft, such as the B-17 bomber, B-47 Stratojet and F-14 Tomcat.


The start and finish line is located at the Aviation Pavilion: 9304 E Marginal Way S, Tukwila, WA 98108.

We recommend and encourage that wherever possible, participants carpool to the race. There is abundant parking close to the start/finish area.  Participants are NOT allowed to park in the Main Museum Campus lot.  Please see the Fly 5K Parking Locations Map for the two parking areas where participants must park.  Arrive on time as E. Marginal Way will close at 8:25am for the race starts.


All awards will be mailed for 2021! Awards will be given to the top 3 overall men and women. 


Each and every Orca Running race supports a charity. Aviation for Humanity is the charity partner for the Fly 5K. A portion of every entry fee will be donated to Aviation for Humanity, and in addition, race participants can opt to make an additional donation at the time of online registration. Aviation for Humanity is a nonprofit organization that works with the traveling public to bring school supplies to children in underfunded schools, shelters, and orphanages around the world.



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. You can review our full set of policies here.
