Background on the race:

In the past eleven years the PI Race has donated over $220,000 dollars to local charities. This successful event is driven by a leadership team of 5th graders from our school. Each year a new race crew of students build on the prior years’ success. Our fifth graders work hard to secure sponsor donations, organize race details, create marketing materials, utilize our runner database, and organize event day festivities. They have created a signature event for this school and our community. This year we need your help to make this the best race yet.

PI Day Run/Walk:

The Leonardo da Vinci School (Green Bay’s school for Gifted Learners) Race Board is planning it's eleventh annual Pi Day Run. We are going to continue taking on initiatives to have an impact that make a difference. We are Altruistic - We give back to the community. The run will take place in Green Bay and be open to the public. This project is being organized by fifth graders, who will work out all the details of the race from designing the t-shirt , creating sponsorship levels, meeting with city and county officials, mapping out the race route, signing up runners, voting on a charity along with all race day details.

Why a PI Run?

The number Pi is approximately equal to 3.141592653589793238462643383… and is the circumference of any circle divided by its diameter.

Event Charity: Old Glory Honor Flight

Mission
Honoring Local Veterans One Mission at a Time.


Old Glory Honor Flight was founded in 2009 by a loyal group of volunteers based in Appleton, WI. We are dedicated to our mission of "Honoring Our Local Veterans One Mission at a Time" which includes all veterans who served prior to May 7, 1975.

The Old Glory Honor Flight missions are completely free of charge to the veteran; we believe it's a meaningful way to say 'Thank You' for their service. Every detail of their day-long trip has the vets' best interest in mind to ensure they have a safe, memorable trip and one that conveys appreciation and admiration from our community. On each flight, we travel with trained volunteers who act as guardian escorts, a volunteer medical team, professional photographers and a host of others like the D.C. Park Police who ensure the veterans get the 'red carpet' treatment.

To receive a shirt in the correct size registration must be completed by Feb 20th

Sorry, NO pets allowed to participate in the race.

Again we look forward to you joining us for the PI race. All proceeds from this race will be donated to Old Glory Honor Flight
