Career

Jana Koščak began her athletic career with AK Sloboda Varaždin, training under her father, Patrik Koščak. Her international breakthrough came at the 2022 European Athletics U18 Championships in Jerusalem, where she won gold in both the heptathlon (6106 points) and pentathlon, setting five personal bests and placing fifth on the European U18 all-time heptathlon list.

Despite an elbow injury limiting her javelin throw, she outscored competitors by over 300 points. In January 2023, she cleared 1.90m in the high jump, breaking Blanka Vlašić’s Croatian U18 indoor record, and a month later set a European youth best in the pentathlon with 4232 points at the Tallinn Indoor Meeting.

In May 2023, Koščak made her senior debut at the Hypo-Meeting in Götzis, finishing ninth with a Croatian senior national record of 6293 points in the heptathlon, the highest score ever by an U18 in a senior event. This performance earned her the “Rookie of the Meet” award, surpassing her sister Klara’s previous record of 5615 points.

In February 2024, she set a national pentathlon record of 4436 points in Tallinn, which she improved to 4478 points at the 2025 World Athletics Combined Events Tour Silver meeting in Tallinn, further solidifying her dominance.

Koščak’s crowning achievement came at the 2024 World Athletics U20 Championships in Lima, Peru, where she won gold in the heptathlon with 5807 points, leading a European podium sweep. Her standout high jump of 1.81m and resilience despite a weaker hurdles performance highlighted her versatility.

With personal bests like 13.26 in the 100m hurdles and 15.11m in shot put, she continues to train for major events, including the 2025 World Championships and the 2028 Olympics. Her rapid rise and record-breaking performances mark her as a future leader in multi-event athletics.
