Ultra-endurance athlete Catherine Breed this week became the first person to swim California’s entire 900-mile (1,448 km) coastline, completing the journey from Oregon to Mexico in less than four months, according to organizers of the Swim California expedition.
Breed, 33, a San Francisco Bay Area native, confronted treacherous currents, storms, sharks and sewage during the journey. Organizers said she swam a steady crawl stroke for up to five hours a day over the course of 111 days.
