At the 1920 Olympic Games, Tuulos won a gold medal in the triple jump. The 14.50 meter jumps he made during the qualifying round was counted for the main event and were enough for the win.
Tuulos won bronze medals at the 1924 and 1928 Olympics. In the long jump, his best result was a fourth place at the 1924 Olympics.[1]
Tuulos improved the European record in triple jump twice: on 20 July 1919 in Tampere with a result of 15.30 meters and on 6 July 1923 in Borås with 15.48 metres.[2] The latter result stayed as the European record for over sixteen years, until Kaare Strøm jumped 15.49 metres in 1939.[7]
Tuulos was the uncle of the Olympic figure skater Kalle Tuulos. He died in Tampere, aged 72.[1]
