The Pi Run and Piece of Pi(e)

Tuesday, March 14, 2017 @ 6:00 PM - 8:00 PM


The new start time for The Pi Run and Piece of Pi(e) is 6:03:14 PM. We have made this adjustment in order to have post-race festivities indoors. A big shout out to Hudson Mills Metropark for working with us during this unexpected cold spell and allowing us to use their indoor Activity Center!

We understand that the new time may inconvenience some of you. We will still have a wave starting at our original start time of 6:28 PM.

The Pi Run and Piece of Pi(e)
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 proudly presents The Pi Run, Michigan’s Original Pi Run, presented by Achatz Handmade Pie Co.: 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 Pie Eat and Run 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 3.14 miles 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.

Is 3.14 a bit too much Pi? Give our Piece of Pi(e) event a try! You’ll run or walk one mile through the park, with all the finishing touches the full Pi Run has to offer!

The Pi Run is walker friendly!



The Pi Guy is Back!

Our special guest for this year’s Pi Run is The Pi Guy, Riley McLincha! A native Michigander, McLincha once held the Guinness World Record for memorizing Pi: he memorized it to 7,500 decimal places. McLincha joined us for our inaugural Pi Run and will be back in 2017, participating in the 3.14-mile run while demonstrating his own unique creation, “drubbling,” which involves dribbling three basketballs in a juggling pattern while running. Be sure to watch for The Pi Guy out on the course!

Here’s Pi in Your Eye!

About that 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-day 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. 🙂

  4. stewart February 10, 2015 at 1:21 PM #

    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. 🙂

  8. Michelle January 30, 2016 at 6:34 PM #


    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?

  11. Mik January 13, 2017 at 8:59 PM #

    The pie in the face at the end of the finish line in 2015 were kinda weak, but in 2016 they were great! What will 2017 hold for us runners?

    • Eva January 13, 2017 at 9:11 PM #

      Well, Mike, that is a great question- and thank you for the feedback on our “Pie-in-the-face” volunteer groups! In 2015, we had a girl scout troop – still very early in target practice. In 2016, we had the U of M Triathlon Club. A solid group of athletes. Good to know they did their job well, but not too much aim involved in their sport. Maybe for 2017 we’ll look for a group with solid hand/eye coordination like a tennis team or pickleball club. Handball, perhaps? Please know, that whateven group we get, our intention is for you to have a top-notch experience! Glad to hear you have been with us for the past two years and I hope to be seeing a pie in your face at the finish line on 3.14.17!

      • Mik January 15, 2017 at 9:59 PM #

        Haha, great response, thanks for the reply! I think both groups did their job well, just the first group could have used quite bit more inside their tins! Hopefully this year will be similar to last year! Looking forward to it! PS: I had never heard of pickleball and had to google that!

  12. Lindsey March 15, 2017 at 1:55 AM #

    Hello! I was unable to attend the race, is there a place I can go to pick up my shirt?


    • ana March 15, 2017 at 7:20 AM #

      Hi Lindsey! Sorry you couldn’t join us. You’ll find details about how to receive your race shirt under Mailing Race Items on our Policies page at https://epicraces.com/Policies.
