[4][5] Sułek graduated from XI Sports High School in Bydgoszcz and, as of 2022, was a student of Journalism and Social Communication at Maria Curie-Skłodowska University in Lublin.

[8] In July, she placed fourth in the heptathlon at the World Championships held in Eugene, Oregon, totalling 6672 points and beating Małgorzata Nowak's Polish record dating back to 1985 by 56 pts.

[9] She wrapped up her long season the following month by taking silver at the Munich European Championships, where she lost injured (biceps femoris problems) only to two-time Olympic champion Nafissatou Thiam.

[10] She achieved altogether four heptathlons over 6400 points that year to secure her first overall World Combined Events Tour victory, becoming only the second Polish athlete after Włodarczyk in 1998 to do so.

Finishing first the 800 m run, the final of the five events in pentathlon, Sułek held the new world record for about six seconds only and had to settle for silver, however, as Thiam set even better mark of 5055 pts.
