Several efforts were made to provide facilities for physical education. In 1896, a cricket pavilion was built, and work began on a polo field. A year later, training in cricket, football, field hockey, and tennis was started. Following Aitchison's win in local sports competitions, the Aitchison Challenge Cup was established to honor the best sportsmen each year. In 1905, ACOBA (Aitchison College Old Boys Association) was established to allow the alumni of the school to compete against the current students in an event that brought together the alumni each year. In 1907, Aitchison College started sending contingents of sports teams to compete with schools outside Lahore and was allowed to host contingents from other schools. Swimming facilities were developed in 1923 and the Rani of Mandi Cup was established to honor the best swimmer of the year. The sports system soon evolved as competitions between the houses began in 1928. Hockey and tennis courts were established in 1938.
