Rdest entered car racing in 2012 when she, as reigning Polish Junior Karting Champion, was scouted by BMW Motorsport. They would enter her in the final round of the Formula BMW Talent Cup for rookie drivers at Oschersleben, where she would finish all three races in the top 10 and finish 10th in the standings despite only entering the one event.[4] She would move up to the BRDC Formula 4 Championship the following year, joining Douglas Motorsport alongside Sennan Fielding.[5] Competing alongside more experienced drivers in open-wheelers, she would struggle to 18th in the standings having completed the full season and scoring a best finish of 11th at Snetterton – however, despite the lack of results, she would claim the "Who Zooms" award for the most overtakes over the course of the season.[6]
She would move into one-make racing for 2014, entering the Central European Volkswagen Polo Cup.[7] She would end the season 14th, with a best result of 6th in her home race at Tor Poznań before stepping up to the Audi Sport TT Cup for 2015.[8] Rdest would compete in all three sanctioned seasons of the TT Cup, with a best result of second at both races in the 2017 season-opener at the Hockenheimring, and a best championship position of 6th in the same season.[9] She would move across to GT4 competition in 2018, remaining with the Audi marque through German team Phoenix Racing and competing in both the International Cup with Max Hesse (finishing 9th) and the Central European Cup round at the Nürburgring alongside Óscar Tunjo, scoring a pole and race win.[10]
Rdest would be selected to qualify for the W Series in 2019, and would be accepted as one of the 18 permanent drivers.[11] She would score points in the first race at Hockenheim, however would be taken out by Esmee Hawkey in Zolder and struggled to thirteenth in Misano. She would qualify fourth at the Norisring, but sustained front wing damage in a first-corner skirmish with Fabienne Wohlwend and finished 14th and a lap down. A season-best sixth-place finish would follow at TT Circuit Assen, before 13th in the final round at Brands Hatch saw the Pole fail to automatically qualify for the 2020 W Series – ending the championship in 14th.
Rdest would return to GT racing in 2020, contesting the French-based Alpine Europa Cup.[12] This followed a class win at the washed-out Dubai 24 Hour in January. She would be announced as a reserve driver for 2021 W Series season and would fulfill her role replacing Tasmin Pepper at the Red Bull Ring. She would place 9th in the first round, and 17th in the second after colliding with her team-mate Marta García.[13] Rdest made her last W Series start at Spa-Francorchamps, deputising for unwell Irina Sidorkova – having narrowly avoided a pile-up in qualifying, she finished last in a wet race some 15 seconds behind second-last.[14]
Rdest remained in the Alpine Europa Cup in 2021 and 2022, finishing 8th in the standings in the former with a podium at Magny-Cours. In 2024, following an 18-month break on maternity leave, she returned to motorsport through the same series.[15]
