Summary
- Breed will swim 900 miles along California's rugged coast.
- She faces risks including sharks, storms, and hypothermia.
- The expedition aims to raise ocean conservation awareness.

In the coming month, Catherine Breed, 33, plans to embark on an unprecedented 900-mile swim along the entire California coastline. Departing north of the California-Oregon border, she aims to reach the Mexican border in 80 to 126 days.
Breed will live and sleep aboard a sailboat with a four-person crew, swimming five to eight hours daily. The expedition, Swim California, faces numerous dangers including great white sharks, storms, and hypothermia. A support team will ensure her safety and logistics.
Beyond the physical challenge, Breed's swim intends to promote ocean conservation. Public education events are planned at key locations to raise money and awareness for issues such as kelp forest health and the dangers of offshore oil drilling.
Breed, who has a background in competitive swimming and has completed other marathon swims, is meticulously planning this expedition. Her preparation includes rigorous training and a comprehensive support system, including a physician and a logistics coordinator.
The endeavor is expected to cost approximately $500,000, funded by individual donors and corporate sponsors. Breed will also use the platform to share her journey through Instagram and YouTube livestreams.
