Throughout the year, Christ's College boys compete in one-off events around Christchurch and further afield.
This is NOT an official sport, with boys who compete coming from athletics, swimming, cycling or team sports.
Regular events include the CSS triathlon and CSS duathlon. Boys can also compete in the NZSS triathlon and other multisport events on the calendar.
