After nearly four months in the Pacific, Catherine Breed finished her California swim about two miles offshore, celebrating with her crew on a sailboat. There would be no final scramble onto the beach at the border. Sewage pollution had put that stretch of coastal water on her team’s danger list long before she arrived.

Breed completed the journey on Monday, October 19, after setting out from the Oregon border on July 1. The New York Times, in reporting published by GV Wire, put the distance at roughly 890 miles, ending off Tijuana at the California–Mexico border. The expedition’s own materials round the route to 900 miles.

A finish planned around polluted water

The offshore approach was no last-minute surprise. In an October 16 interview with KPBS, Breed said the pollution near Imperial Beach had been flagged in her planning spreadsheet from the start. Her crew was tracking beach closures and intended to keep her away from the shoreline. The plan then was about a mile offshore; the later finish report placed her farther out.

KPBS described a coastline where sewage pollution has repeatedly closed beaches. Breed had spent months trying to cover a state’s worth of ocean, yet people living beside that final stretch could not reliably use the water outside their homes. Bringing attention to that problem was part of the point of the expedition.

Swimming a state, one stage at a time

This was a supported stage swim, not an uninterrupted 900-mile effort. Breed wore a wetsuit, and the Swim California media kit explains the setup: nights mostly aboard the support boat, visits ashore, and rest days built into the schedule. The boat gave the team a base between long days in the water.

The Times reported 18 days out of the water for rest or dangerous weather, with more than nine miles covered on an average swimming day. That rhythm stretched across more than 100 days.

The uncertainty lasted almost to the finish. In her October 11 update from Dana Point, Breed wrote that the crew was waiting out bad weather with 75 miles remaining. She had allowed until November 5 in her worst-case schedule, but was aiming for October 19 if she could average 11 miles a day.

That same update described stops with coastal communities and conservation groups, including Santa Barbara Channelkeeper and The Bay Foundation. Swim California’s stated aim was to connect people with the coast and the problems facing it, alongside the athletic challenge.

The World Open Water Swimming Association was still ratifying the swim when the Times report appeared, so the completed expedition should not be confused with a finalized record certification.

For Breed, the immediate adjustment was simpler: the swimming was over. “It feels surreal being done, this has been my entire life for nearly four months,” she told the Times after finishing.
