Born in Maribor, she won a bronze medal in the 1994 Winter Olympics in Lillehammer. She took her sole World Cup win at the age of 18 in a Super-G in Flachau in December 1993, taking victory from a bib number of 66, a few days after Markus Foser had won at Val Gardena with the same start number. Koren was the first woman to take an Alpine Ski World Cup win for Slovenia, a couple of days after Jure Košir became the first man to win a World Cup race for Slovenia as an independent nation in Madonna di Campiglio.[2]
She retired from skiing in 1998, due to a spinal injury.
Since 2008, she has been active in politics, and has run twice on the electoral lists of the Slovenian Democratic Party.
