Pi Day 5K

Lace up your running shoes for the Pi Day 5K, a truly unique and heartwarming event taking place on March 14, 2026, in Green Bay, Wisconsin. This annual 5K run/walk is more than just a race; it's a vibrant community event orchestrated with incredible dedication by a race board of fifth-grade students from Leonardo da Vinci School. These young organizers handle everything from route planning and t-shirt design to securing sponsorships and runner registration, showcasing impressive leadership and commitment. Typical race day conditions in mid-March often see comfortable highs around 40°F and lows near 24°F, with only an 8% chance of precipitation, making for invigorating running weather.

The Pi Day 5K kicks off and concludes at the Leonardo da Vinci School, located at 139 S Monroe Avenue. While specific course details on elevation are not extensively detailed, the route is expected to traverse Green Bay's city streets. Past events suggest parking near Grace Lutheran Church and city lots by Cherry Street, indicating an urban course. Participants can look forward to packet pick-up at the school gymnasium the day before or on race morning, with the race program starting outside on Doty Street. Upon crossing the finish line, runners are greeted with post-race snacks and the chance to view raffle items, all contributing to a festive atmosphere.

Beyond the personal achievement of completing a 5K, every step taken in the Pi Day 5K supports a significant cause. All proceeds from this event are donated to Old Glory Honor Flight, a dedicated charity that honors local veterans. Having raised over $185,000 for local charities in its decade-plus history, this student-led race offers a genuinely impactful way to celebrate Pi Day while giving back to the community. Join in this inspiring tradition and experience a race that truly makes a difference.
