About this race
Join us for the second annual Math Medic Foundation Pi Day Pi K Presented by NumWorks! Each participant will receive a T-shirt and finisher medal with this year's one-of-a-kind race logo. Participants can choose to run virtually with their friends and family OR choose to run in-person at one of our 6 locations around the country. Check the details of each location to see if one of them is right for you.
Teachers, this year you can sign up your class - student registration is just $5π. Students can sign-up individually through this registration page or you can contact Pete Grostic, [email protected], for bulk registrations. Ask your administrator or PTO if they'll cover the cost for your class. Each fee goes to a great cause - helping students, teachers, and schools in need. 100% of funds raised will go to the Math Medic Foundation Scholarships and Grants fund.
Don't care to run? No problem! Walk, run, bike, crawl - it's just 1.95 miles, you can do it!
Can't run on 3/14? Don't sweat it! Complete your Pi K early or up to a week late.
$10π a bit too much?
Don't worry, through donations, fundraisers, and referral codes, there are many ways to get your registration fee refunded. Start the Sign Up process to find out how!
Thank you to our sponsors!
