POSTPONED to 6/28 (2pi) – Pi Day “Pi K” Fun Run/Walk 2020 (Better than a 5K!)

Fleet Feet Chicago Running Stores

ISC’s fun – and tasty! – Pi Day Fun Run is back for the 8th year!

Join us for a GREAT event. Whether you run, walk, amble, strut or skip you’ll support science outreach programs year-round.


Run Start & Course:

The 3.14-mile “Pi K” run or walk starts at 10:00am at three Fleet Feet Chicago-area stores. Doors open at 9:30 for you to get your t-shirt and trivia quiz. Locations for 2020 are: South LoopLincoln Square, and Oak Park. (To quote the Grail Knight in Last Crusade, “Choose wisely” there is a fee to change locations.) Go to to reserve your spot.

The course route will be determined by Fleet Feet running experts and maps will be available at check-in and possibly in advance.


Each runner who registers by Friday, March 6th will receive a Pi K t-shirt. After that, we can’t guarantee supply or sizes. The ISC-branded Pi K shirt is made of cotton and will be available in small, medium, large and x-large.

Packets & Party:
There is positively NO PACKET PICKUP prior to the run but there will be a pie party after!

T-shirts, swag, and Pi Day quizzes will be picked up at check-in on race day. Bag check is available at the stores and you can change clothes there, so please arrive early. Post-run, back at Fleet Feet, we’ll have bagels & coffee, pie, and a trivia quiz with prizes!

Awesome Sponsors!
ISC is thrilled to partner with Fleet Feet Sports, Chicago’s top running source, for this fun annual event. If you are interested in sponsorship opportunities, email Monica at

This is Chicago. Weather on March 14 could be warm and sunny, or cold, windy and wet. You know how to dress accordingly. Pi K takes place rain, snow or shine. If cancellation is warranted due to severe weather conditions, announcements will be made on the day of the run, not in advance. Even if the run is cancelled, the pie party probably won’t be. We’re not savages. There are no refunds but transfers are allowed.

The Significance of Pi:
Pi, in case you don’t remember, is abbreviated to 3.14 but continues indefinitely. To date, it has been calculated by computer to over 1.2 trillion digits. Competitions exist for reciting the most digits by memory. As the world’s most famous mathematical constant, Pi is important to many formulas used in mathematics, science, engineering and statistics.

All Pi K proceeds support the public science outreach programs of IL Science Council, a 501c3 organization. Your body benefits because you’re exercising it with a slightly elongated 5K.
Your brain benefits from cardio exercise, thinking & learning about pi, plus exercising it with our trivia quiz.
Your heart & mind benefit because you appreciate that all event proceeds benefit ISC’s efforts to bring engaging public programs on science, technology, engineering and math to our community.
