Arild Lenth (20 November 1904 – 28 March 1972) was a Norwegian long jumper and triple jumper.
His personal best long jump was 7.18 metres, achieved in July 1928 on Bislett stadion.[1] In August 1928 at the same stadium he jumped 14.11 metres in the triple jump, another career best.[2] At the 1928 Summer Olympics he competed in the long and triple jump. In the long jump he achieved 6.60 metres and failed to reach the final; in the triple jump he achieved 13.39 metres and again failed to reach the final.[3] He became Norwegian champion in the long jump in 1928 and 1929, representing Hamar IL. He also won the national bronze medal in 1927.[4] He became Norwegian triple jump champion once, in 1928.[5] He did not hold the triple jump club record in Hamar IL, as Lauritz G. Bryhn had jumped 14.28 metres in 1921.[2]
Lenth chaired the club Hamar IL from 1946 to 1947.[6] Together with Guri Bakke (1910–1989) he had the son Borger Arildssøn Lenth (b. 1937), a jurist and banker.[7]
