Natalia Kaliszek

In 2014, Kaliszek began competing with Ukrainian ice dancer Maksym Spodyriev for Poland, coached by Nowak-Trębacka in Toruń.[5] The two made their international debut at the Volvo Open Cup, where they took the junior silver medal. Switching to the senior level, they placed sixth at a Challenger Series (CS) event, the Warsaw Cup, before winning gold at the Santa Claus Cup. They won the Polish national title at the Four Nationals in December 2014 and took bronze the following month at the Toruń Cup.

Kaliszek/Spodyriev were selected to represent Poland at the European Championships, held in late January 2015 in Stockholm, Sweden. Ranked fifteenth in the short dance, they qualified to the free dance, where they placed fourteenth and rose to fourteenth overall. In early March, they made their second and final appearance on the junior level, competing at the World Junior Championships in Tallinn, Estonia; they placed tenth in the short dance, sixth in the free dance, and seventh overall. Later in March, they traveled to Shanghai, China for the World Championships, but were eliminated after placing twenty-fourth in the short dance.

Kaliszek/Spodyriev competed in three 2015–16 Challenger Series competitions. After placing seventh at the Nebelhorn Trophy, they won bronze at the Mordovian Ornament and silver at the Warsaw Cup. They finished third in the Challenger Series ranking.[6]

Kaliszek/Spodyriev placed eleventh at the 2016 European Championships in Bratislava, having ranked eleventh in both segments. At the 2016 World Championships in Boston, they placed fourteenth in the short dance, sixteenth in the free dance, and sixteenth overall. At the end of May 2016, it was announced that the International Skating Union had chosen the foxtrot portion of their short dance to become a pattern dance.[7]

Starting their season on the Challenger Series, Kaliszek/Spodyriev placed fourth at the 2016 CS Ondrej Nepela Memorial and fifth at the 2016 CS Finlandia Trophy, in early October. During training in early November, they had a fall, related to poor rink conditions in Toruń, that resulted in her blade cutting two of his fingers.[8] Later in the same month, they debuted on the Grand Prix series, having received invitations to two events.[9] The duo finished fifth at the 2016 Cup of China and seventh at the 2016 NHK Trophy.

In January 2017, Kaliszek/Spodyriev finished 8th at the European Championships in Ostrava, Czech Republic. In March, they placed fifteenth in the short, thirteenth in the free, and fourteenth overall at the 2017 World Championships in Helsinki, Finland. Due to their result, Poland qualified a spot in the ice dancing event at the 2018 Winter Olympics in Pyeongchang, South Korea.

Kaliszek/Spodyriev began the season with a tenth place finish at the 2017 CS Finlandia Trophy, the first of two Challenger events the team would take on that year. On the Grand Prix, they placed ninth at Skate Canada and eighth at the Internationaux de France. Following the end of the Grand Prix, they won gold at the 2017 CS Tallinn Trophy, followed by a bronze medal at the Santa Claus Cup. They repeated as champions at the Polish Figure Skating Championships for the fourth consecutive time, and were named to Poland's Olympic team, as well as to the European and World championships.

Competing at the 2018 European Championships, Kaliszek/Spodyriev placed tenth. Competing at the 2018 Winter Olympics ice dance event, they placed fourteenth in the short dance. Kaliszek/Spodyriev were one of three teams in the competition whose rhumba pattern dance made use of the song "Despacito", along with South Koreans Yura Min / Alexander Gamelin and the Chinese team of Wang Shiyue / Liu Xinyu. The effect of the song's ubiquity was heightened further because Kaliszek/Spodyriev and the Min/Gamelin skated consecutively, and attracted comment on social and entertainment media.[10][11] The duo qualified for the free dance, where they placed fifteenth, and fourteenth overall. They concluded the season at the 2018 World Championships in Milan, Italy, where they placed seventeenth.

The 2018 CS Nebelhorn Trophy marked Kaliszek/Spodyriev's first event of the new season, placing eighth. On the Grand Prix, they placed sixth at Skate America and fifth at the Rostelecom Cup. Following the Grand Prix, they competed at the 2018 Warsaw Cup, winning the silver medal behind Tiffany Zahorski / Jonathan Guerreiro. They went on to compete in two more Challenger events, winning the bronze medal at the Tallinn Trophy and a silver at Golden Spin. In December, Kaliszek/Spodyriev won their fifth national title.

Competing in the rhythm dance at the 2019 European Championships, they placed fourth, and were the only team to receive a perfect score on the Tango Romantica pattern dance.[12] They placed fifth in the free dance, and fifth overall.[13] They placed eleventh at the 2019 World Championships.[14]

The pattern dance based on Kaliszek and Spodyriev's 2015–16 "Tea for Two" short dance, formally known as the Tea Time Foxtrot, was adopted for use in the junior international competitive season. Kaliszek and Spodyriev spent much of the preseason teaching the dance at seminars for junior dance teams.[15][16]

Beginning the season at the 2019 Shanghai Trophy, they won the bronze medal there, before winning silver at the 2019 CS Ice Star.[14] On the Grand Prix, they placed sixth at the 2019 Internationaux de France.[17] At the 2019 Rostelecom Cup, they placed fourth in the rhythm dance despite a serious error on the Finnstep pattern dance, exiting hold midway through.[18] They remained in fourth place overall following the free dance.[19]
