About this race
The Fifth Annual Jack William O’Brien 5K honors a young man remembered for his contagious smile. Jack lived an outdoorsman lifestyle and worked hard in the trades; the fund helps others live their legacy. Expect smiling faces, music, food, and raffles. Early bib pickup for the Smile Like Jack Family Fun Run/Walk is at the Knox Trail Inn.
