Arundell was born on Cyprus in 2002, at the then Royal Air Force base in Dhekelia; a Sovereign Base Area and British Overseas Territory. He spent the first two years of his life on Cyprus before moving back to the United Kingdom.[3]
Arundell started his sporting career at a young age, excelling at various sports while a pupil at Holt VC Primary School.[6] He subsequently attended Beechen Cliff School in nearby Bath. After his father joined the staff of Harrow School, Arundell enrolled at the all-boys London boarding school, putting him in the catchment area for London Irish's academy, which he joined aged fourteen.[7]
Club career
London Irish
In the Premiership Rugby Cup in 2022, a number of Arundell's performances drew attention, including two tries against Leicester Tigers in a semi-final;[8] a 20-minute substitute appearance against Wasps, scoring a try and being named Man of the Match,[9] and a try that started on his own goal-line against Toulon.[10][11][12]
His performances for London Irish saw him named as Premiership Rugby's young player of the season for 2021–22.[13] On 10 June 2022, Arundell signed a new "long term" contract with London Irish.[14]
Racing 92
After London Irish collapsed into administration in June 2023, Arundell joined Grand Paris-based French side Racing 92.[15][16] After the Rugby World Cup, he played his first game for the Sky Blue and Whites at Toulon on 12 November and scored a hat-trick in a 31–26 narrow loss.[17]
