The Courtney Lynn Blakeslee Foundation just held its biggest fundraising event of the year on Saturday: the Courtney’s True Blue 5K.

The foundation helps children with terminally ill parents enjoy themselves like other kids — whether at ball games, fishing trips or festivals — without the additional financial strain on the families.

The foundation was founded in memory of Courtney Lynn Blakeselee, who lost her short battle to cancer on July 20, 2010, leaving behind two young boys.

Her sister Lindsey runs the nonprofit.

“While caring for Courtney when she was sick we had several conversations, however two left a lasting impression on me,” Lindsey writes on the foundation website. “The first while looking out the window onto the city street Courtney said, ‘What I would do to run.’ The second, ‘When I get better I’m going to give back.’”

“We want to unite these children that understand what it is like to lose a parent, so they are not alone,” Lindsey writes. “It is our hope, to get together and celebrate several times a year whether it is a fishing trip, ball game, festival or a picnic.”
