Catherine Breed Passes 500-Mile Mark in California Coast
Open water swimmer Catherine Breed has swum over 500 miles of her 900-mile 'Swim California' expedition. The 33-year-old former Cal swimmer aims to be the first to swim the length of the state's coast.
Catherine Breed has swum more than 500 miles of her planned 900-mile journey along the California coastline. The 33-year-old from Mill Valley began her staged open water swim at the Oregon-California border on July 1, with the goal of reaching Mexico.
According to a September 8 progress report tracked by the World Open Water Swimming Association, Breed is now more than halfway through the attempt. The swim, dubbed 'Swim California,' is organized through Breed's nonprofit, Sea Dreamers, which aims to connect women to the ocean and promote environmental stewardship.
Expedition Progress and Logistics
Breed swims in stages, with a support boat ensuring the route is connected into one continuous effort. GPS waypoints track the path between her entries and exits. The World Open Water Swimming Association reported that favorable currents and several long swimming days put Breed roughly ten days ahead of schedule by late August. She crossed Monterey Bay ahead of plan, arriving at Hopkins Marine Station in Pacific Grove on August 25, which marked the 455-mile point.
Progress along the Big Sur coast presents logistical challenges due to limited harbors and changing sea conditions. The expedition includes planned stops where Breed and her team meet with local conservation groups.
Breed's Background and Motivation
Catherine Breed swam competitively for the University of California, Berkeley before transitioning to marathon open water swimming. Her previous solo swims include crossings of Monterey Bay and from the Golden Gate to Half Moon Bay, as well as an English Channel crossing.
She founded the nonprofit Sea Dreamers to frame this attempt. The organization seeks to connect women to the ocean through adventure, education, and community, building environmental stewardship along the way.
"Grit is my superpower, but you cannot do hard things alone," Breed said. "This isn't just about swimming."
Ratification and Record Potential
The World Open Water Swimming Association is reviewing the swim for potential ratification. Observer logs and documentation are being collected throughout the expedition. A final ratification decision will not be made until the swim is complete and the full record has been submitted and reviewed.
If she successfully completes the entire 900-mile route, Catherine Breed will become the first person to swim the length of the California coast. The swim remains ongoing as she continues south from the Big Sur region toward Mexico.
