Yorkshire Rows is a team of four formidable working mums who dared to dream. They are the first women to row across the North Sea and holders of a Guinness World Record for rowing 3000 nautical miles across the Atlantic Ocean during what has been described as the world's toughest rowing race, the Atlantic Challenge. The crew left La Gomera in the Canary Islands and completed the 3,000-mile challenge reaching Antigua 68 days later. In doing so, they became Guinness World Record holders as the oldest all-female crew to row across any ocean. They've just published a book, Four Mums in a Boat, about their experience.
