Stephanie Clutterbuck
British long-distance triathlete who swam competitively into her late teens and then rowed at university before back problems ended that career in 2018. She took up triathlon as an age-grouper, winning Ironman Portugal in 2021 and Ironman Vitoria-Gasteiz and the 70.3 age-group world title in 2023, and was picked for the Zwift Academy Triathlon team. Turning pro in 2024, she rides strongly: she set the fastest women's bike split on her way to second at Ironman Chattanooga, which earned her Kona debut in 2025 on a Ventum Tempus.
