He received the LOU MARSH TROPHY as Canada's athlete of the year in 1949. He continued to do well after 1954, when the shorter waterfront marathon was replaced by a 30-mile (48 km) swim across the lake. In 1956 he won the Atlantic City 26-mile (42 km) event and became the second man (after Bert Thomas) to conquer the Juan de Fuca Strait. Later, he coached his daughter Kim and assisted Cindy NICHOLAS and other marathon swimmers.
