Julie Kole, 17, of Fallston, will compete at the World Swimming Championships in Perth, Australia next month.
Kole, who swims for the Foxcatcher Swim Team at Germantown Academy in Philadelphia, was chosen to replace another swimmer, who dropped off the team because of a virus. She will swim the 800-meter freestyle event and the freestyle relay.
Originally, Kole had been chosen for the U.S. team to compete in Perth as a member of the 4x200-meter freestyle relay team. She had elected not to make the trip, so she could stay in class and prepare for exams at Germantown.
