Pie Day Pi K

Durham, NC

Pi Day is celebrated around the world on March 14th (3.14).  


Pi Day is not just for math geeks anymore...  it is now PIE Day for foodies, runners, and walkers!

Plan to join us on Sunday, March 13, 2022 for the Pie Day Pi K 3.14 Kilometer (1.95 mile) race at C.M. Herndon Park in Durham. 

Race Your Way

Choose whichever style race you're comfortable with:
  • Traditional "Mass Start".  For those who prefer the competition of a mass start race, check in between 8:00 and 8:55 AM and line up for the 9 AM gun start.
  • Socially-distanced Time Trial.  Many runners love our "Safer COVID Time Trial Style" race format. Show up any time between 9:00 and 10:00, check in to get your race bib, and head to the start line for your race. Run individually or with your friends/family.
  • Virtual Race: Run when and where you want.  Complete your 5K any time between March 13th and March 31.  You may pick up your shirt on race (or have a friend pick it up for you)
Pie Day Pi K is part of the 2022 Triangle Race Series.
