22,000 Miles Later, Adventurer Prepares For 3,000-Mile Solo Row Across Atlantic

For most transatlantic travelers, a trip from London to Cape Cod takes about nine hours, including getting to and from the airport. For 29-year-old Sarah Outen, the journey has lasted nearly four years. But it was hardly a direct route! Outen has so far traveled 22,000 miles on a self-propelled round-the-world voyage.

The trip has included 11,000 miles of biking and kayaking across Europe and Asia; 150 days alone at sea, rowing between Japan and Alaska; 1,500 miles in her kayak through the treacherous Aleutian islands; followed by 5,000 miles across the United States and Canada by bike.

In addition to the sheer challenge of the trip - which she named "London2London: Via the World" (L2L) - Outen is traveling to raise money for four charities: Coppafeel, which raises awareness and funds for breast cancer; the MND Association for research into motor neurone disease; Wateraid, an international organization promoting clean drinking water and the Jubilee Sailing Trust.

Now, Sarah Outen is preparing for her last 3,000 mile solo rowing trip across the Atlantic, to end up in London, where she began her trip in 2011. If she completes the four-month trip, she'll be the first woman ever to row the route. She joins Here & Now's Robin Young by Skype from Cape Cod to talk about the journey to come.
