The son of an Essex fishmonger, Samuel Hunter served in the Royal Army Service Corps in World War I. He continued his cycling career after the War, and in 1922 was selected as a reserve for the Great Britain team for the World Amateur Road Race Championships on home soil. The following year he was on the team at Zürich, but finished in 29th. That same year, Hunter, a member of the Warren Cycling Club, won the coveted Bath Road “100” Time Trial. In 1924, he was a member of the British road race team at the Olympics. However, he had the misfortune of puncturing four times, and was involved in a spill which resulted in him finishing 34th, and last of the four Great Britain riders. An engineer, Hunter went to live and work in Maracaibo, Venezuela, shortly after his Olympic appearance. In 1928 while back in England on holiday, he was involved in a motor car accident when the vehicle he was travelling in was involved in a head-on collision in North London. Fortunately, it was not fatal and Hunter returned to South America. A proficient pilot, he obtained his Aero Club licence in 1939..
