Rice senior Ella Dyson dominated the women’s field en route to winning the event for the second straight year and fourth overall, producing a time of 56:05.7 to comfortably top the runner-up, teammate Ava Portello, by a minute and 41 seconds.
The swim from Dyson was remarkably more than seven minutes faster than she went en route to winning the event last year (1:03:31.0), though the entire field was significantly faster this year, indicating conditions were much more favorable.
Portello, who was 7th last year, touched in a time of 57:46.7 to comfortably place 2nd, dropping nearly 10 minutes off her time from 2024.
Villanova’s Marlene Blake took 3rd in 58:31.1, while Rice’s Ava Hamblett placed 9th in 59:18.0 to give Rice the team victory in a time of 2:53:10.
Rice’s win marked its third straight at the CSCAA Open Water Championships.
