Marchant had little formal training and only took up the sport at the age of 16 because his friends liked the sport.  In 1955, Marchant shot to prominence after only two years in the sport, winning the 500 m time trial and the 5 mile event at the Junior Australian Championships.  This resulted him being approached by Browne to team up in early 1956 and they promptly won the tandem event at the national championships to earn national selection.  The pair were eliminated after losing their first two races but were given a reprieve when the Soviet Union pair were hospitalised in a crash and forced to withdraw.
