Ella Dyson, a senior at Rice University not only handily won the 2025 MPSF Open Water Swimming Championships in Long Beach, California (see here), but she is also the defending champion at the upcoming 2025 College Swimming & Diving Coaches Association of America (CSCAA) National Collegiate 5K Open Water Swimming Championship in Sarasota, Florida.
From West Coast to East Coach, the British swimmer from Marlow, England (born in Melbourne, Australia) has dominated the collegiate open water scene. In Long Beach, she won by nearly a minute over Rice teammate Ava Portello, and by over 3 minutes over second place Miriam Frass (@miriam.frass) of Youngstown State University in Florida last year.
Dyson ultimately hopes to return to Southern California for the LA28 Olympic open water swim. But she has a lot of racing to do before then, including the 2025 CSCAA Open Water Championship that will take place on December 13th at Nathan Benderson Park in Sarasota. USA Swimming has designated the event as an approved qualifying event for its national championship. The top five finishers for each gender earn invitations to the USA Swimming 5K Open Water Championships.
Rice coach Seth Huston is known for his passion for open water swimming and has attracted some of the finest women open water swimming in the collegiate ranks, leading the Rice women to the 2022 and 2024 CSCAA Open Water Swimming National Championship titles – hoping for a third title this year. Huston said, “Ella and Ava and their teammates push each other every day in practice.”
