The Pi Run
presented by Achatz Handmade Pie Co.

Mark your calendars: the granddaddy of all mathematical holidays is coming up. That’s right! We’re talking about the annual 3.14. Such an epic date deserves recognition beyond the realm of math… and that’s where we come in!


Have Your Pi and Eat It, Too

Epic Races, Michigan’s premier endurance and multi-sport race event company, proudly presents The Pi Run, Michigan’s Original Pi Run, presented by Achatz Handmade Pie Co., and the race that celebrates this circle-related number … and the circular edible it brings to mind. At 6:28 PM on Tuesday, March 14, 2017, participants will run or walk a 3.14-mile loop (as fans of π, we like to think of the course as a circle) at picturesque Hudson Mills MetroPark. And, since this is all about Pi, we’ll kick off the event with a special Pi(e) Wave: a pie-eating division in which competitors start their run or walk once their pie plate is empty. Don’t want to hit the trail on a full stomach? You can still commemorate Pi Day with our optional Pie in the Face at the finish line!

Aiming for a Pi R? Need a little encouragement along the course? The Pi Run will feature pacers from the Ann Arbor Running Company, ready to help you run your best 5K ever! We will have pacers for 7:00, 8:00, 9:00, 10:00, and 11:00 pace times. Watch for the pace team at the starting area; they’ll be the ones in matching Ann Arbor Running Company shirts, holding pace signs.

The Pi Run is walker friendly!


Goodies Galore!

Our Pi Run participants will receive:

  • race chip timing with results posted within 6 hours
  • a fabulous circular finisher’s medal
  • a high-quality, super-soft race T-shirt (T-shirt sizes are not guaranteed after Feb. 26)
  • free downloads of their race photos, taken by Greg Sadler Photography
  • post-race pie and more pie, featuring apple and berry pies!
  • a Virtual Race Bag featuring offers from our sponsors!


Virtual Spoiler


Join us in S-Pi-rit!

Can’t make it to the race? Have your own private π celebration? No problem! The Pi Run has a virtual option, so you can run or walk for π anywhere: on a treadmill, around your neighborhood, even in Pi-ttsburgh or Mississip-Pi! You’ll still receive our fabulous finisher’s medal and super-soft T. Here’s what you need to do:

  • Complete your 3.14 miles by Tuesday, March 14
  • Take a screenshot of your sports-tracking smartphone app showing the distance or of your GPS watch with the completed mileage
  • (Optional) Post the photo on the the Pi Run Facebook page.. and be sure to tell us about your ex-Pi-rience! If you’re Tweeting about your Pi Run, be sure to tag @epicraces in your Tweet!

Your race goodies will be mailed out to you shortly after the completion of the actual Pi Run event.

Please note: Epic Races does not ship swag to Canada or internationally. If you are a resident of Canada or another country and wish to participate in an Epic Races virtual event, please provide us with a U.S. shipping address.


Let’s Circle Back and Sum That Up!

The Pi Run has THREE race divisions:
• The Pi Run, in which participants will run (or walk) 3.14 miles
• The Pi Pie Run, the pie-eating division in participants will eat a 6-inch pie in the traditional pie-eating-contest style (no hands) before beginning their 3.14 mile run.
• The Virtual Pi Run, in which participants will run (or walk) 3.14 miles wherever in this circular world they may be.

NewGovCouncilThe first two divisions will have overall and age group awards (scroll down for age groups), and all finishers will receive a sweet 3.14-diameter medal!

The Pi Run is part of the Pure Michigan FITness Series of events and is endorsed by the Michigan Governor’s Council on Physical Fitness, Health, and Sports.


Make Your Buddy Hap-Pi!

Epic Races recognizes the compassion, support, and friendship that exists between a runner and their I Run 4 buddy. To help your buddy feel more special, we’ve created a race add-on so that your buddy can receive his or her own Pi Run medal. We applaud those runners who dedicate their miles to buddies with special needs whose conditions span the spectrum from total physical disability to developmental delays to autism spectrum disorders and more. Look for the IR4 add-on when you register, or log into Run Sign Up to manage your registration and add the IR4 add-on. For more information on the I Run 4 program or to be matched with a buddy of your own, visit the I Run 4 web site.

Pieces of the Pi

Can I pay my park entrance fee with pie?
We wish! But unless you have an annual Metropark permit, you’ll have to pay a $10 per vehicle admission fee.

Do I get anything special for finishing the race in 31:41?
Yes! You receive applause and the right to be recognized as the Ultimate Pi Runner!

I missed online registration and now I’m unhapPi.
No worries! We’ll have race-weekend registration, where you can sign up in person for the race.

π is an infinite number. Does that mean I have to keep on running and running?
Remember that π also does not repeat, so you are officially done after completing the 3.14-mile loop.

I’d prefer walking the Pi Run. Is that okay?
Absolutely! You can run, jog, walk, skip, cartwheel, dance, crawl… whatever makes you hap-Pi!

Can I dress up like Albert Einstein for this race?
Well, Albert wasn’t a mathematician, but 3/14 is his birthday, so go right ahead! Or maybe consider an Isaac Newton costume, since Newton was a mathematician and is sort of associated with … apple pi.

It’s been a few years since I was in school. What is π again?
Pi, or π, represents a mathematical constant: the ratio of the circumference of a circle to its diameter. For basic calculations, π is recognized as 3.14159, although in actuality it has been calculated to more than one trillion digits past the decimal point. It’s an irrational number and continues infinitely without repetition or pattern. And don’t worry… we aren’t irrational and will not require you to memorize π. Unless you really want to.

    I would love to do the run at the metropark, but I won’t know until about a week in advance if I can make it there (due to my kids schedule that day). If I sign up for the virtual race, can I switch and come to the real event if I find out I am available? I would want to sign up in time to get a shirt, not wait until I know their schedule for that day.

    • ana February 6, 2015 at 8:23 PM #

      Yes, absolutely! All you would need to do is find the “Solutions” area at the on-site registration center the morning of the race and let us know you signed up for Virtual and want to switch to the actual run. We’d be more than happy to help get you set!

  2. Jeremy February 8, 2015 at 2:53 PM #

    Hi there, are strollers allowed? We’d like to run with our two infants. Thanks!

    • Eva February 9, 2015 at 2:02 PM #

      Yes, Jeremy. Strollers are allowed, but please start toward the back and plan on “jogging” as opposed to “running”. Thanks for asking!

  3. Gabriel February 9, 2015 at 4:39 PM #

    Do the volunteers get a shirt also?

    • ana February 9, 2015 at 6:05 PM #

      Gabriel, yes! We will have volunteer Pi shirts. 🙂

    What kind of pie is used in the pie eating division?

    • Eva February 10, 2015 at 1:24 PM #

      Achatz Pie! You will have your choice of flavor. 🙂

  5. Megan February 16, 2015 at 12:26 PM #

    I too am in a similar situation as Beth…I will not know for a while if I’ll be able to make it. I plan on signing up for the virtual, but if I’m able to make it to the actual race then I would definitely like to run in the Pi(e) division. Is this particular switch possible?? I understand that there’s a difference in the race fee and am happy to make up that difference.


    • ana February 16, 2015 at 1:03 PM #

      Yes! Just look for the Solutions area at the Registration Tent on race morning and we will take care of you. 🙂

    • Eva February 23, 2015 at 1:15 PM #

      Hi Megan,
      Go ahead an sign up for the virtual. If you are able to come race day, visit the solutions table and we will make the change for you!

  6. Karl February 23, 2015 at 12:56 PM #

    Q: Is the Pi Run shirt a Tech Fabric type material or is it a Cotton type fabric? Being such technically astute runners, “super soft” is just not enough info. Type of fabric makes a difference in size selection for myself and likely others. Thx in adv.

    • Eva February 23, 2015 at 1:14 PM #

      Hi Karl,
      Technically, it is a tech shirt because it is not 100% cotton and it is wicking. It is not your typical tech shirt because it is not that typical slippery fabric, it is super soft. For the women’s fitted shirt, we suggest sizing one or two sizes up- it IS fitted. The unisex fits true to size. If you like loose fitting shirts I suggest ordering one size up. We do have shirt exchange available after the race based on availability. Please let me know if I can help with anything else.

  7. Michael February 26, 2015 at 2:55 PM #

    How can i get people hit with pie at the finish line?

    • ana February 26, 2015 at 4:42 PM #

      We will be selling pies at the event for $5 each, with the proceeds benefiting Dexter Community Schools. Once you are armed with your pie, just watch for your Pi Runner and then go for it! Runners also have the option of running through the “Pie in the Face” chute at the finish line. 🙂

    Is this a dog friendly event?


    • ana January 30, 2016 at 7:07 PM #

      Hi Michelle! Sorry, but for safety and liability reasons, dogs are not permitted on the course.

  9. Jenny January 30, 2016 at 8:17 PM #

    IT sounds like a great event. Any discount or extra goodie for having a Pi birthdate?

    • ana January 30, 2016 at 10:45 PM #

      We’re more than willing to lead the Pi Run participants in 3.14 rounds of “Hap-Pi Birthday to You!” If you’d like. ?

  10. Jen Hilla March 4, 2016 at 7:01 PM #

    Do you need volunteers?
