Marcellin in the early 1950’s had their annual Athletic Carnival at Xavier College on a Sunday afternoon. In 1955 it was held at Camberwell Oval on a Wednesday afternoon. Every boy at the school competed in at least one event. Each age group went from A Division through to H with the winners of A division going to the Associated Catholic College Competition.
In 1954 the Associated Catholic Colleges of Victoria held the Annual Athletic Sports at North Melbourne Cricket Ground. All 8 schools competed in the same race but the results were as two divisions:
St Patricks College Ballarat
St Josephs CBC Geelong
Marist Brothers College Bendigo
St Patricks College Sale
Marist Brothers College Mt Gambier
Marcellin College Camberwell
Christian Brothers College Warrnambool
It was recorded that the only Marcellin winners against the 8 schools in 1954 was the Under 13 440 team of Peter Ruddock, Francis Connelly M Powell and Geoff Kelly
The Marcellin boys had little or no training as there were no facilities at Canterbury Rd . The only area to train was a 15 yard strip at the back of the shelter shed which was used for long jumps .The boys competed just on natural ability.
In 1958 the Associated Catholic Colleges held the Annual meeting at Olympic Park the schools competing were now:
CBC Victoria Parade
CBC St Kilda
CBC North Melbourne
St Bedes Mentone
Each year Marcellin competed against Carey and Carey Old Boys in an athletic competition on a weekend at Carey .
