|Competitor for Estonia|
He competed for Estonia at the 1924 Summer Olympics held in Paris, France where he won the bronze medal in the men's decathlon competition. He was also very strong in many individual events, placing 5th at the 1920 Olympics in the javelin throw. In 1922 he became the first official world record holder in the decathlon, albeit with a performance inferior to the Stockholm 1912 series of Jim Thorpe. He Estonized his surname to Kolmpere in 1936.
