In 1948 Aage Larsen teamed up with the Danish single sculls champion from 1946-48, Ebbe Parsner to win their first Danish double sculls title the same year. This victory earned them a trip to that year’s Summer Olympics where they were defeated by Great Britain’s Dickie Burnell and Bert Bushnell in the final and settled for silver. Parsner and Larsen found continued success nationally and internationally, however, winning Danish and European titles, as well as the Double Sculls Challenge Cup at the Henley Royal Regatta, in 1949 and 1950. The duo competed at the Olympics again in 1952, but were eliminated in the round one repêchage. Outside of sports, Larsen, a Danish naval veteran of World War II, worked as a machinist at the DFDS shipyards in København. In 1962, Larsen moved to Fredensborg, where he operated a gas station until his retirement in 1986.
