[2] She produced a career tally of nine medals, including a silver in skeet shooting at the 2004 ISSF World Cup final in Maribor, Slovenia, and was selected to compete for Finland in two editions of the Olympic Games (2000 and 2004).

Having pursued the sport for more than two decades, she trained full-time for Satakunta Shooting Club (Finnish: Satakunnan Ampujat) in her native Pori under personal coach Lauri Siltavirta.

[5][6] At the 2004 Summer Olympics in Athens, Lepomaki qualified for the second time, as the oldest athlete of the Finnish team (aged 47), in the women's skeet.

[7] Less than two years before the Games, she had registered a mandatory minimum score of 65 and eventually won the gold medal at the ISSF World Cup meet in Suhl, Germany, occupying one of the available Olympic quota places for her team.

[8] Lepomaki aggregated a total record of 67 out of 75 clay targets to share a three-way tie with 2000 Olympic silver medalist and world record holder Svetlana Demina of Russia and 43-year-old Kim Yeun-hee of South Korea for the ninth position, failing to advance to the final round.
