A Sun Prairie ninth-grader died while working out at Sun Prairie High School on Thursday afternoon, according to a letter sent to faculty and parents from Cardinal Heights Middle School Principal Ryan Ruggles.
Jay Haraldson,16, was taken to St. Mary's Hospital, but efforts to revive him were unsuccessful, Ruggles said in the letter.
Nancy Harms, Haraldson's summer swimming coach, said he had taken part in swimming practice in the morning and was doing fine afterwards.
"The news spread rapidly yesterday," Harms said. "He collapsed when he was working out at the high school on the treadmill. The adults that were there did everything they could. They started CPR and the EMS got there very quickly."
Jay's father Joel and mother Sharon, who is a teacher at Patrick Marsh Middle School, watched their son endure some of life's challenges.
