Catherine Breed completed a historic swim along the California coast this week, navigating a series of environmental challenges posed by El Niño conditions. The endurance swimmer began her journey in Brookings, Oregon, and finished at the U.S.-Mexico border in Coronado, California.
Breed, a former collegiate swimmer sidelined by knee injuries, shifted her focus to open-water distance swims after graduation. Over time, she established herself in the Bay Area swimming community by undertaking increasingly ambitious challenges. Her most recent endeavor, a continuous swim tracing much of the California coastline, was closely monitored by the World Open Water Swimming Association, which highlighted the coordinated efforts of the support crew aboard the Catalyst, a 52-foot sailboat that served as Breed’s base throughout the trip.
The support team managed logistics such as studying wind patterns, ocean currents, and plotting daily routes to capitalize on optimal swimming windows. Their routine included early mornings starting in darkness and afternoons dedicated to maintenance, meetings, and meal preparation. The coordination allowed Breed to focus on the demanding physical task of swimming while managing unpredictable weather and ocean conditions.
El Niño played a significant role in complicating the swim, mixing waters in an unusual manner and bringing tropical storms, hurricanes, and the Kelvin wave into the region. These factors prompted adjustments to the original route, including swimming certain legs from south to north to circumvent strong currents. Despite concerns about marine life hazards, Breed reported minimal issues with jellyfish and distant shark sightings, attributing her safety partly to maintaining a distance of one to five miles offshore—also a strategy to avoid man-made obstacles such as crab pots.
Breed described varying conditions throughout the journey. Some days featured calm seas and memorable encounters with local wildlife including dolphins and sea lions. One notable moment occurred near Big Sur when she rested aboard the Catalyst after a day’s swim as her team enjoyed the waters. However, other segments were arduous, underlining the physical and mental demands of the swim.
Reflecting on the experience, Breed said she would not recommend attempting the entire route to others but encouraged people to engage with the ocean in ways that suit their comfort levels. She expressed hope that her undertaking would motivate more individuals to appreciate and protect the marine environment. Breed cited the desire to inspire others as a key motivation, comparing her swim to other extreme endeavors like climbing Mount Everest or rowing across oceans.
Shortly after completing the swim on Monday, Breed returned to ocean activities, spending Tuesday surfing at Point Loma. She described the experience as a welcome break from the structured demands of the swim, emphasizing the joy of simply being in the ocean with friends.
