Tell me more!


Maybe you love math, maybe you love running, maybe you love pie.  Maybe (probably) you love all three.

The Pi Day Dash brings all of these elements together in one glorious fun run event.

Come celebrate with us on Pi Day in 2020!  March 14th!

Who can participate?

Pi(e) lovers of all ages are invited to the Pi Day Dash!  There will be a free Cutie Pie Dash for kids age 6 and under, with free pie-pops at the end.  Kids under 18 are welcome and encouraged to run or walk the full 3.14 miles, but must have a parent or guardian register them. Strollers and leashed dogs are welcome at the Pi Day Dash, but we ask that you please position yourself near the back of the start line.

Where and when?


Saturday morning, March 14th, 2020 at Magnuson Park in Seattle getting ready to take off for a 3.14 mile run or walk inside the park!  The post-race pie party will be in Hangar 30, just in case it's cold or rainy outside.  March can be unpredictable, so we thought we'd make it easier to enjoy your pie by keeping it indoors!

Included with registration:


Pi Day Dash shirt, gear check, awards, free photographs, and a post-race pie party

100% of the proceeds generated by the Pi Day Dash are donated to the Leukemia & Lymphoma Society.  This amazing event is made possible by boatloads of volunteers, generous sponsos, and Pi(e) Lovers like you!  Our goal is to raise at least $31,415.92 for this great organization.  For more information about the Leukemia & Lymphoma Society and how they are working to cure cancer, check out  If you are running in honor of someone impacted by cancer, please email and let us know.  The mission means a lot to the Pi Day Dash crew, and we love to hear how our participants are standing together.  Thanks!
