Background
Sophie O’Sullivan needs no introduction. Daughter of one of Irelands most prolific achievers at international level, Sonia O’Sullivan, the Ballymore/Cobh AC athlete comes with a line of accomplishments at the tender age of 23.
Sophie started her athletics career at High Jump earning an All-Ireland medal at underage. In Australia where she grew up, she participated in multiple sports but it was running that always drew her back in – winning races despite very low mileage compared to her peers. Her first success at international level came with a silver medal at the u18 Europeans in Hungary in 2018. While she did compete the following year in the u20 Europeans, the Australian born athlete had to wait a further four years for a podium finish. It was then in 2023 that she made history by becoming the first Irish athlete to take gold at an u23 European Championship. At college in the US, the University of Washington Communications graduate had her big career moment earlier this summer when she became only the fifth Irish person to win an NCAA championship. O’Sullivan stormed to victory in the 1500m in Oregon to take the NCAA title.
At senior level, O’Sullivan has competed in the Paris Olympic Games, one World Indoors, along with three NCAA track finals. Tokyo will be her second World Championship appearance.
