24 June 1973
On 24 June 1973, South African athlete Danie Malan set a new world record in the middle distance 1000m event in Munich. Malan was raised in the Boland area of the Cape, where he took part in athletics from a young age. Malan began to take athletics seriously during his last two years of high school, and won the national under/17 title for the 400m race in 1967. After school, Malan obtained a Bachelor of Science (BSc) from Stellenbosch University, where he also excelled in athletics. However, Malan's most famous event was the 1000m race in Munich, in the stadium which had hosted the Olympics the year before. There he set the world record time for the event, at 2.16.0. South Africa's isolation from international competition from the 1970s hampered Malan's ability to compete internationally. However, Malan was invited to Zurich in 1976 nevertheless, where he also set the world record for the 1500m event.
