Lynne completed four swims in the Arctic paying tribute to the great polar explorer Roald Amundsen, who was the first to traverse the Northwest Passage by boat in 1903 – 1906. Lynne sets the record for the coldest swim – 1/4 mile at 26.6 degrees Fahrenheit off Disko Bay – a record that stands today.
Highlighting her concerns for the environment: Lynne was invited by the Sierra Club and Rivers Unlimited to advocate for maintaining high standards for water quality. Joined by many local athletes, her swim from Cincinnati, Ohio to Newport, Kentucky was successful – the community’s water standards were maintained.
In one of her most noted accomplishments, Lynne was the first person to complete a 1.2 mile swim in Antarctica, from the ship Orlova to Neko Harbor in 25 minutes wearing only swimsuit, cap, and goggles.
Swimming from Bolivia to Peru, Lynne became the first to swim across Lake Titicaca. She had support from the Bolivian Navy and a welcoming committee from Peru and the National Swim Team of Bolivia. Her swim enhanced relations between the two nations.
Lynne continued her collaboration with a joint US-Soviet team to become the first person to swim across Lake Baikal. In recognition of her accomplishment, the Soviets named a cape on Lake Baikal in her honor – Cape Lynne Cox.
After years of seeking permission, preparation, and planning, Lynne achieves a diplomatic first swimming across the Bering Strait to open the US-Soviet Border for the first time in 48 years with a time of 2 hours and 6 minutes in 38-degree water.
Continuing her effort to garner support for the Bering Strait swim Lynne completed a series of challenging swims around the world including waters in the US, Iceland, the Strait of Gibraltar – becoming the first person to swim from Morocco to Spain, Strait of Messina, around Delos Island in Greece, the Bosphorus, Lake Kuming in China, the 5 lakes of Mount Fuji, Glacier Bay, and finishing at the Golden Gate.
Seeking support for her future Bering Strait swim, Lynne completed ten swims in the highest, coldest, and most difficult waterways in the United States including Lake Tahoe, Lake Winnipesaukee, Lake Madison, and the Golden Gate.
Achieving a new milestone, Lynne became the first person to swim across the Strait of Magellan. She swam in 42-degree F (5.5 degrees C) water, through a storm with a 9-knot cross current, in 1 hour 2 minutes.
Lynne was the first woman to swim across Cook Strait between the North and South Islands of New Zealand. After being pushed back by currents for 5 hours, she completed a 20 mile crossing in 12 hours and 2 ½ minutes. This swim was heralded by New Zealand’s Prime Minister Rowling as having helped heal relations between his country and the United States.
Lynne was invited to compete in an international swimming race in the Nile River by the Egyptian government. The water was extremely polluted and during her training in the river Lynne became very sick. She competed in the race anyway and she passed out and was pulled from the water.
Shortly after her 1972 swim, Lynne’s record was broken by Davis Hart. Rising to the challenge, she returned to England and regained the men’s and women’s records for swimming from England to France, with a time of 9 hours and 36 minutes.
