In 2021 Oli turned 16 and had the opportunity to get his ARDS test, which he passed just after his 16th birthday. Oli’s Dad had been racing Legends for a few years by now, also with Mickel Motorsport, so he was familiar with the cars and the format. He had a couple of races with Legends towards the end of the ‘21 season and managed to get some positive results, despite having to start from the back. For 2022 , his first full season, he ran a full Legends campaign and he set his sight on the Rookie Championship. There was very stiff competition and Oli was just pipped to the Rookie title by a few points leaving him to claim 2nd place. He  went on to study motorsport mechanics at college but decided in 2015 that working within the family business at Kalimex was more appealing. In his spare time he  loves to play rugby for Haywards Heath RFC.

In 2023, at just 18, Oli came a very close 4th in the National Championship and 9th in the Elite Cup (BTCC). He also received the 'Most Improved Driver' 2023 in the Elite Cup Championship. In 2025 Oli stepped up further collecting a third place podium in both Elite Cup and the National Championship.
