IBU Cup
Before receiving a spot in Ukrainian national team, she took part in IBU Cup competitions. Her first World Cup race was in Swedish Östersund in 2014–15 season where she finished 51st in individual. There she also competed in sprint finishing 87th. Then she missed two World Cup stages returning in Oberhof, Germany. Since Ukrainian team lacked its leaders (both Sochi Olympic champions Vita Semerenko and Olena Pidhrushna missed that season) she was invited to relay team. Merkushyna did her job well by shooting without additional shots. Nevertheless, her personal results weren't good enough to debut at World championships. Next season she spent in IBU Cup competitions.
