The 2025 USA Swimming Open Water National and Junior National Championships are held at the Nathan Benderson Park in Sarasota, Florida this weekend under the direction of Macie McNichols.
The 5 km and 10 km races are the qualifying events for the 5 km and 10 km individual events at the 2025 World Aquatics Championships in Singapore held in July. In addition, all the qualifying swimmers can be selected to the USA Team Relay and 3 km Knockout Sprints at the World Championships.
April 4th is the men’s and women’s 10 km national race. April 5th is the men’s and women’s 5 km Junior 5 km race. April 6th is the men’s and women’s national 5 km race and the 7.5 km Junior National race.
On the women’s side, 2024 Olympians Mariah Denigan (MSF bio here), Katie Grimes (MSF bio here), Claire Weinstein, and Emma Finlin of Canada, World Championship swimmer Abby Dunford of Canada, and fast contingents from Australia, Japan, and Canada will be in the mix with the top American open water swimmers.
But there is one swimmer – the oldest in the field – who presents a wild card with her decade plus of national-level and international experience: 27-year-old Becca Mann (MSF bio here, @becca__mann). She is expected to be in the mix and certainly part of the lead pack, having competed in her first open water swimming national championship at the age of 13 in 2011 (also held in Florida). The USC graduate has competed in the 400m individual medley, 800m freestyle, 5 km, 10 km, and 25 km events at three previous World Championships (in Barcelona, Spain, Kazan, Russia, and Budapest, Hungary).
She recently released her second book, Outside the Lanes, A Pro Swimmer’s Story of Resilience, Reinvention, and Redefining Success, available on April 8th.
