Heregger started skiing at the age of three and came to the ski club in her home town of Irschen in Carinthia through her father . After secondary school in Dellach im Drautal , she attended the Schladming ski trade school . After her first of three Austrian youth championship titles, she was accepted into the squad of the Austrian Ski Association in 1994 , whereupon she drove her first European Cup races in the winter of 1994/95 and was used at the 1995 World Junior Championships . In the 1995/96 season Heregger reached the first podium finishes in the European Cup, with which she was fourth in the overall European Cup and won the giant slalom discipline with the same number of points as Barbara Milani and Andrine Flemmen . At the Junior World Championships 1996 in Hoch-Ybrig , she was the most successful participant with two gold medals in downhill (February 27th) and combination (March 2nd) and a silver medal in giant slalom (February 29th). Combined gold she owed her further rank 27 in the slalom; She also finished 5th in the Super-G. She also made her first two starts in the World Cup this winter - she made her debut on December 20, 1995 in the Super-G in Veysonnaz - but remained in the beaten field (45th place) ).
After the good European Cup results of the previous year, Heregger was initially used regularly in the World Cup in winter 1996/97. However, she was never able to score and was therefore returned to the European Cup from mid-January, where she achieved numerous top 10 results, but hardly any podium finishes. The few World Cup appearances in the next two years were again unsuccessful with placings beyond the top 30, until Heregger surprisingly reached eighth place in the downhill run from St. Moritz on March 5, 1999 and thus won her first World Cup points. After this first World Cup success, Heregger continued to play primarily in the European Cup in the 1999/2000 season , where she was able to improve her results significantly compared to previous years and, with three wins and a further eight podium places, won the overall and giant slalom rankings. In the second half of the season she started again in the World Cup, where she was now able to place regularly in the points and achieved her second top 10 result in tenth in the Super-G in Innsbruck .
From the 2000/01 season , Heregger was an integral part of the Austrian World Cup team. Among other things, with two further top 10 placements in Cortina d'Ampezzo in mid-January (eighth in the Super-G and ninth in the downhill), Heregger secured a starting place for the 2001 World Cup in St. Anton am Arlberg , in which she (with the start number 2) unexpectedly reached third place in the downhill and thus ensured an Austrian triple victory behind Michaela Dorfmeister and Renate Götschl . Heregger also started in the World Cup combination, but was eliminated in the first slalom run. In the following season 2001/02 Heregger reached after further top 10 placements in the World Cup two podiums when she was second in the sprint downhill and third in the combination of Åre in early February . At the 2002 Winter Olympics in Salt Lake City , Heregger finished sixth in the downhill and eleventh in the combination, only in the giant slalom she was eliminated.
In the 2002/03 season , however, Heregger fell far behind. Her only result among the top 20 was 15th place in the Super-G in Cortina d'Ampezzo, whereupon she was increasingly used again in the European Cup. Due to an injury, Heregger had to take a break from mid-December in the next winter of 2003/04. Then she scored only a few points in the World Cup in the 2004/05 season, but still one victory in the European Cup before she ended her career at the end of winter. Heregger began training as a masseuse and opened Café Selina in Irschen.
