Born in Dubai, Koloc began her sporting career in tennis at the age of four before an injury prevented her from furthering her career. After taking part in a test in one of her fathers' racing trucks in early 2019, she switched to motorsport with the goal of competing in the Dakar Rally.[4] Starting out in trucks, her program quickly grew to accommodate stock cars, GT4 and rally raid in order to improve her versatility, leading to a title in the FIA Middle East Cup for Cross-Country Bajas in 2022 ahead of her Dakar debut.[5][6]
