This race is a fundraiser to benefit the John Patrick Flanagan Foundation, a local non-profit founded in 2009 in memory of John Flanagan who lost his battle with cancer at the age of 44. JPFF's mission is to help vulnerable children and families by supporting charities that provide the direction, education, and a healthy environment that vulnerable children and families need to have the opportunity to reach their full potential.

We have enabled nearly 5,000 inner-city children to go on field trips to the CT Audubon Society in Fairfield as part of the John Patrick Flanagan Trailblazers program. We've funded programs and college preparation assistance for inner-city teens, helped economically disadvantaged immigrant women and children learn English and life skills, helped children battling cancer, have supported children affected by HIV/AIDS, and sponsored volunteer attorneys who work to place children in safe permanent homes and given scholarships to children who have a financial need as well as children who have lost a parent to cancer.

Thank you for your support for the John Patrick Flanagan Foundation.
JPFF is a 501(c)(3) tax-exempt organization, Tax ID number 26-4783810.

Our 'chip-timed' 5k event takes place in Greenfield ‘Hill’ but our 3.1 Mile course is not hilly! The gently rolling course is shaded on tree-lined streets, going past sweeping stone walls, horses, and open spaces. It is a truly picturesque setting!


The Shamrock Sprint is hosted on-site at the CT Audubon Nature Center. After you're finished we encourage you to walk through the great trails on the Audubon property. It is a perfect cool-down activity with friends, family or on your own to enjoy the native flora and fauna. CT Audubon memberships are available!

Stay for the after-race party for great food and lots of fun.

This event will be held rain or shine.
