Benefiting Blood Cancer United
Pi Day - March 14
Greenlake Park, Seattle, WA
Get ready for a fun, flaky crust of excitement at our Pi Day Dash! It's not just a race; it's a celebration of circles, slices, and everything nice. Run or walk the 3.1415 miles around scenic Greenlake, where the course is as flat and fast as a freshly rolled dough. And for the little runners, there's the Kids Dash Mini Pi, a sweet .314-mile race. But wait, there's more than just running! Show off your memory skills in the Pi recitation competition, dazzle in the costume contest, and if you've still got room, dive into the pie eating competition. Mark your calendars for this deliciously irrational event full of pie puns and good times!
