The annual Cross Country and Track and Field events organised by Clonmel AC are hugely anticipated in St. Mary's CBS. For weeks in Autumn and Summer the boys prepare for the school trials before selection on the team to represent the school at Marlfield and The Dr. Pat O'Callaghan Centre each year. The School Sports day is also a great day for all the boys with the annual sixth class high jump competition a highlight for all - pupils and teachers alike.
