A few weeks after winning that silver medal in the 400 metres at the 2019 European Athletics Indoor Championships in Glasgow, Bolingo felt a pain in her Achilles that got worse and worse and finally forced her to scrap the entire 2019 season.

[2] On 1 June 2021, she broke the Belgian record on the 400 metres at a meeting in Montreuil, France; with a time of 50 seconds and 75 hundreds, she improved upon the 16-year-old time of 51 seconds 45 hundreds by Kim Gevaert, and qualified to compete at the 2020 Olympics.

In June 2024, she was on the Belgian 4 x 400 metres women's relay team that won a bronze medal at the European Athletics Championships.

[7] The injury prevented her from running in both the 4x400 women's and mixed relays at the 2024 Summer Olympics denting Belgian teams's chances for a medal.

In the only race she did compete in at the Olympics, the women's 400 metres, an obviously not fit Bolingo finished a disappointing 42nd in the heats.
