Educated at King’s School, Canterbury, Alan Barrett went on to become a doctor working at Guys Hospital and the London Hospital, and later in Malta. He rowed for both Guys and The London, and also for the London Rowing Club (LRC), and was in their crew that won the junior eights at the 1932 Kingston Regatta. Two years later, at the Henley Royal Regatta, the LRC was beaten by the Thames Rowing Club by one-third of a length in the Thames Challenge Cup. Barrett turned his attention to fours in 1936 and represented LRC in the Stewards’ Challenge Cup at Henley that year before going to win a silver medal in the coxless fours at the Berlin Olympics.
