During his freshman year, John wanted to quit track and field. Not an unusual decision. Distance track isn’t for everyone. It’s tough. Easily one of the top mentally and physically challenging sports in high school. Throw in the inevitable injuries and you have a tough road. John Bresnahan persevered through all of these tests and completed 8 seasons of distance track and cross country to become an incredible GBS role model. - Coach Hilvert (2020)
