Kaur hails from Rasalpur Kalan, a village near Amritsar. Her mother Jasbir Kaur encouraged her to take up sports professionally. She lost her father at the age of six and was raised by her mother.

Kaur became the first Indian woman to clinch a 20 km Race Walk silver medal in the Asian Games by bettering her personal best and setting a new national record in the process.

The 21-year-old from Amritsar clocked 1:33:07 to improve on her previous personal best of 1:33:37, which was also the national record, to finish second at the Marathon Course.
