Loen made his international debut at the 1974 World Curling Championships in Bern , but he remained without a medal. In 1976 he won his first precious metal with the bronze medal at the Junior World Championships in Aviemore .
Loen played as the third of the Norwegian team in the XV. 1988 Calgary Winter Olympics in curling. Skip Eigil Ramsfjell's team won the Olympic gold medal after a 10-2 win in the final against Switzerland under Skip Hansjörg Lips . Since curling was still a demonstration sport at that time, the medal has no official status.
