Emil Väre (Vilén) of Finland was the likely favorite. In 1911, he had won one of four international championships which were contested that year, and in 1912 he also won the European championship. In the competition, he threw all six of his opponents, although the final against Gustaf Malmström (SWE) was a closely fought match, which took Väre a full hour to win. Väre returned in 1920 to defend his Olympic gold medal at Antwerp.
