Charlotte Cassebourne-Stock

Charlotte is a British endurance athlete who trains year-round in the Wasatch Mountains. With a background in competitive rowing, she increasingly gravitated towards mountain sport and has found ski mountaineering a natural combination of endurance, technical skill and adventure.

In the 2025/26 season, Charlotte finished second overall in the US Ski Mountaineering National Cup before being selected to represent Great Britain. In summer, she swaps skis for running shoes and spends much of her time trail and mountain running.

Away from the mountains, Charlotte works in biotechnology, starting and scaling companies that develop new medicines. She lives in Park City, Utah, with her husband Harald and their son Fynn, where movement and time outdoors are an integral part of family life.
