Chester County Food Bank

Even in the best of times, Food Insecurity is a very real problem for many of our neighbors. The Chester County Food Bank was formed in 2009 to address the escalating hunger problem in the county. Their primary goal is to be a viable, sustainable organization that secures, manages and distributes food to those in need.

Today, they are the central hunger relief organization serving more than 120 partner agencies in Chester County, PA. Through their network of food cupboards, hot meal sites, shelters and other social service organizations, they distribute over 3 million pounds to our neighbors with limited or uncertain access to adequate food.

We are asking you, our runners, to consider bringing a donation of non-perishable goods with you on Race Day. Thank you for your generosity!
