Catherine Breed Completes 900-Mile “Swim California” Expedition
By Drooid · · How we work
Background and Prior Endurance Feats
Catherine Breed, a former University of California, Berkeley long-distance swimmer and former US national team member, had already crossed the English Channel (2018) and the North Channel (2019). She also set a record for the fastest swim of Lake Tahoe in 2017 and was the first to swim from San Francisco’s Golden Gate Bridge to Half Moon Bay (2022). These achievements framed her ambition to traverse the entire California coastline—a 900-mile route from the Oregon border to the Mexican frontier.
Timeline of the Expedition
- Early July – Breed launched the staged swim, beginning at the northern border of California.
- Day 40 (August 9) – She paused at Bodega Harbor, addressing a crowd of about 200 supporters and noting a personal shift away from “the black line” of competitive swimming.
- Mid-October (111 days after the start) – The final leg concluded at Coronado Bay, marking the end of the 900-mile journey.
- October 21 (scheduled) – Breed will attend a community gathering in Coronado, hosted by the nonprofit WILDCOAST, to discuss ocean-conservation themes linked to the swim.
Data and Statistics
- Total distance: approximately 900 miles along the California coast.
- Duration: 111 days, averaging roughly 10 miles per day.
- Daily swim on the penultimate day: 9½ miles.
- Wave conditions: encounters with waves up to 7 feet and a “Super El Niño” surge that created strong opposing currents.
- Environmental observations: sightings of humpback whales, dolphins, and extensive plastic debris; water near Imperial Beach described as among the dirtiest in the United States.
Official Statements & Responses
The organization will host a post-completion event in Coronado, featuring remarks from city council member Amy Steward and Breed herself. Breed’s nonprofit Sea Dreamers, which connects women to the ocean through adventure and education, partnered with the event to promote marine-conservation dialogue.

Why It Matters
Breed’s swim combined extreme athletic endurance with a platform for environmental advocacy. By documenting polluted stretches—particularly near the Tijuana River mouth—and engaging coastal communities, the expedition amplified calls for water-quality improvements and marine-habitat protection.
What’s Next
The scheduled October 21 gathering in Coronado will feature a discussion of local conservation initiatives, including kelp-forest restoration efforts led by the Greater Farallones Association. Breed plans to continue leveraging her visibility to support Sea Dreamers’ programs and broader ocean-preservation campaigns.
