Cutting his teeth in Cadet karting, Olli was quick to develop his pure racing skill.
Making his debut in the Comer Cadet class, he took the Southern regional championship in 2012. Honing his racecraft, he moved up to contest the British Championship, Formula Kart Stars - where he was invited to the Bahamas for a special event to showcase his skill.
Finishing the 2013 season seeded 9th in the country in the hugely competitive Super One British Championship, Olli made the early move up to the Junior karting ranks at only 10 years old.
2014 saw him graduate into the Minimax Championship, where he became the youngest ever pole sitter in the Minimax class at Buckmore Park. Battling racers up to 3-4 years his senior, he managed to hold his own and made massive strides in his performance. Earning regular top ten finishes on a national level and competing for podiums in multiple regional championships.
2015 saw Olli move to multiple British Championship winning team KR Sport, winning his first ever Junior Rotax race at Shenington in the Winter Series, before continuing his progress in the Rotax Euro Challenge.
