Runners geeking out.  Math geeks on the run.
Everyone running pi for PIE!!

The typical 5K of 3.1 miles is so old-school. ISC's "Pi K" is so much better because MATH makes it a 3.14-mile run. Or trot, saunter, walk, skip or strut.

Start the spring season off right with a Pi K Fun Run! March 14, or 3.14, is celebrated internationally in honor of the math constant pi. Illinois Science Council, a Chicago nonprofit promoting science and math, teams up with Fleet Feet Sports to honor the importance of pi and running in our lives with a Pi Day 3.14 mile fun run. (Note to our fleet footed rule followers -- we know Pi K technically means 3.14 kilometers, not 3.14 miles, but "Pi K" just rhymes better than "3 point 1 4 mile run." It's an artistic choice.)

Date:  Tuesday, March 14, 2017

Start Time: 6:28pm (or 2pi) at 3 Fleet Feet Sports Locations:

Fleet Feet Sports - Old Town, 1620 N. Wells St., Chicago, 60614

Fleet Feet Sports - Lincoln Square, 4762 N. Lincoln Ave., Chicago, 60625

Fleet Feet Sports - Oak Park, 102 N. Marion Street, Oak Park, 60301

Each location will have a post-run pi(e) party immediately following the run at the Fleet Feet store including pizza, beer, of course pie, and games with prizes (prizes are for mental ability, not run times).

Capacity is neither uncertain nor irrational. Each run venue has a capacity that cannot be increased: 314 people at Old Town location, 157 (1/2 Pi) each at Lincoln Square and Oak Park. So register early and check to be sure to choose your desired location or it will cost you at least $10 to change it later.

The awesome Pi K Run T-Shirt is only guaranteed to runners who register by March 1.

I agree to abide by a decision of a race official relative to my ability to safely complete the run/walk. I assume all risks associated with running/walking in this event including but not limited to: falls, contact with other participants, the effects of the weather, including low temperature/high heat and/or humidity, traffic, and the conditions of the course, all risk being known and appreciated by me. Having read this waiver and knowing these facts and in consideration of my entry, I, for myself, and anyone entitled to act on my behalf, waive and release Illinois Science Council and its officers and employees, DL ZIMCO, Inc. d/b/a Fleet Feet Sports-Chicago and its officers and employees, and all other sponsors, individuals, and volunteers associated with the event, their representatives and successors and all claims of liabilities of any kind arising out of my participation in this event.

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. 


Your body benefits because you're exercising it with a slightly elongated 5K. Your brain benefits because you'll be thinking about and learning about pi (and exercising it with our trivia quiz). Your heart & mind benefit because you appreciate all proceeds of this event benefit ISC's efforts to bring engaging public programs on science, technology, engineering and math to our community.

Illinois Science Council

Illinois Science Council ("ISC") is an independent 501c3 organization that engages, educates, and entertains the adult public about science, technology, engineering and math in our everyday lives. We showcase the scientists and research of those Chicago-area institutions and companies that make Chicago our nation's true "City of Science." ISC serves as the science & tech complement to the region's arts & culture offerings. 

We are inspired and motivated by this Carl Sagan quote: “The brain is like a muscle. When it is in use we feel very good. Understanding is joyous." Sagan also observed, "We live in a society that is exquisitely dependent upon science and technology in which hardly anyone understands anything about science and technology." ISC is certainly working to change that.

ISC explores all areas of science and technology and we do it with a fun, non-stuffy approach.  We don't care what's been forgotten since school (or never learned in the first place). It's simply about continuing to exercise our inexhaustible human sense of curiosity. We create engaging programs open to the public (aimed at adults and accessible to teens) such as hands on chemistry (Chemistry of... Beer, Chocolate, Coffee, Honey, etc), panel discussions on science subjects in the news (Your Brain on Happiness, on Creativity, on Addiction, on Exercise, etc.), author talks, film screenings ("The Atom Smashers"), and more.
