[6][7] Starting out in the French lower-division one-make saloon car championships, Wadoux encountered success from early on, with an 8th place (runner-up in the junior class) in the Peugeot 208 Racing Cup followed by 3rd overall the following year.

[8][9][10] Her 2018 season also included four top-ten finishes from four guest starts in the superior Peugeot 308 Racing Cup, as well as an appearance in a two-day test organised by the FIA Women in Motorsport Commission in Navarra for 15 female racers.

She was hit by Qatari driver Abdullah Ali Al Khelaifi, who had lost control of his Cupra León TCR after an off at turn 16, and her car rolled several times before it finally came to a stop.

[15][16] She returned to racing in October that year, with a one-off appearance in the Clio Cup France at Circuit Paul Ricard that yielded a podium finish.

[22] Continuing in the Alpine Elf Europa Cup with Autosport GP, she finished eight of the 12 races on the overall podium and was part of a three-way title fight with reigning champion Jean-Baptiste Mela and single-seater graduate Ugo de Wilde that went down to the wire.

[28][29] In November 2021, Wadoux, as well as W Series drivers Jamie Chadwick and Alice Powell, was invited by the all-female LMP2 Richard Mille Racing Team to take part in the post-season FIA World Endurance Championship rookie test at Bahrain.

[49] In parallel, she would compete in the endurance rounds of the IMSA SportsCar Championship in LMP2 with AF Corse, partnering Nicklas Nielsen and 2023 teammate Pérez Companc.

[50] After two races where the team encountered trouble, Wadoux contributed towards her first win in the category at Watkins Glen, taking the car from third place to the lead during her stint and being praised by Le Mans winner Nielsen for her pace.

[51][52][53] Wadoux was set to take part in the Formula E women's test at the Circuito del Jarama in Madrid[54] ahead of the 2024–25 season, driving for Jaguar TCS Racing.
