What's included with registration?


You get chip-timed entry into the 3.14 mile run/walk, a super comfy finisher's t-shirt, free photos of the entire event, and the most fun post-race pie party Seattle has ever seen!  Registration is capped at 2,000 participants so make sure you sign up early!


Shirts are only guaranteed to those who register by March 1st.  After that, we'll do our best but we need to order shirts with plenty of time to print and pick them up from our shop in Redmond!

Pricing Schedule

Everything is better with a group of friends!  Sign up with a team (or make your own!) and enjoy a team discount!  In 2015 we had FORTY teams signed up for the Pi Day Dash.  We'll have roaming photographers to capture all your team moments - we'll tag you in them so you can find them in a snap!


Packet Pickup

Stay tuned for packet pickup details.


Day-of Registration

You can risk it and wait to register on race morning, but be warned:  you might not get a shirt and we might be sold out.  That being said, any available race entries will be sold Saturday morning, March 14th, starting at 8am in Hangar 30.  Cash, checks, and credit cards are all accepted.



As with most sports, participating in a race involves a number of inherent risks, including but not limited to tripping and falling, contact with other participants or spectators and the effects of weather, traffic and road conditions. Because the course is run on park paths and trails, there are posts and possible potholes. Additionally, there may be other foot and bicycle traffic on the course. All participants need to be prepared to avoid obstacles and traffic. In submitting your entry, you are acknowledging your awareness and assumption of all risks associated with your participation. You are certifying that you are medically and physically fit to safely compete in this event.  Dogs are not allowed on the race course.
