Thanks to improved covid numbers, we’re super excited to be LIVE again for our 10th Annual Pi Day 3.14-mile Fun Run!! Three cheers for vaccines, boosters, and mask-wearers! Join us in-person on 3/14 at 6:28pm to run a 3.14 mile loop and socialize afterwards. If you’re not ready for people yet, that’s okay, you can select our virtual option. Here’s the plan:

1. REGISTER at PiDayRun.org

Register EARLY (by midnight Thursday, February 24) and we’ll get this year’s awesome PiK t-shirt delivered to you by March 14th to wear on Pi Day.

Register later (until midnight March 14) to have your collectible PiK t-shirt delivered after Pi Day.

Pi & Pie Fans anywhere can join this year — no need to come to Chicago! (There will be a small surcharge to ship t-shirts overseas. There’s math involved.)

All registrants receive this year’s awesome Pi K t-shirt they can wear proudly to show their respect for math and support of science outreach.

2. “RUN” 3.14 something:

In Person: We’ll meet at the South Loop Fleet Feet Sports running store in Chicago on March 14. Be there and ready for the run start at 6:28pm CT (2 PI!!) We’ll have a 3.14-mile route mapped out for you and afterward we’ll have donuts to enjoy in celebration of everything circular.

Virtual: You should run, walk, skip, cartwheel, or saunter 3.14 miles, which is a little more than a 5K. (It’s the honor system. We won’t know if you spent 3.14 hours on your couch.) You can also go 3.14 kilometers, furlongs, acres, leagues, or city blocks if you choose, where you choose! But make sure you are wearing your Pi K shirt, and share your picture on our social media pages.

The Pi K Shirt: 

This year’s collectible tee is in hot pink!!  ISC’s 2022 Pi K Fun Run T-shirt is a softstyle unisex cotton tee in sizes XS – 2XL.

The logo on the front is not some esoteric equation. Rather, it indicates this is a “Pi K” as opposed to a 5K run (a little extra for math), and the exponent number indicates this year, 2022, is the 10th(!!!!) annual run.

The back of the shirt gives a nod to the pandemic and celebration of vaccines with a syringe replacing the numeral 1 in 3.14. The “dividing line” between 3.14 and ISC’s logo is not a line at all. Up close you’ll notice it’s a long sequence of digits of pi. 🙂

All proceeds support the STEM outreach efforts of Illinois Science Council, an independent 501c3 nonprofit based in Chicago that offers creative and engaging science programs for teens and adults.

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.
