Sarah Outen MBE FRGS (born 26 May 1985) is a British athlete and adventurer. Outen was the first woman and the youngest person to row solo across the Indian Ocean and also the Pacific Ocean from Japan to Alaska.
On 1 April 2011, Outen set off on an expedition, a solo loop of the planet called “London2London: Via the World”. She rowed, cycled and kayaked her way eastward from London around the world, sharing stories about the adventure and experience.
The 20,000 miles (32,000 km) journey was scheduled to take 2.5 years to complete. During her expedition, she cycled across Europe and Asia, rowed across the north Pacific, and cycled across parts of the United States and Canada to Cape Cod, before rowing across the North Atlantic to the UK.
The journey took 4.5 years and was all the richer for not turning out exactly as planned. She completed a round-the-world journey at Tower Bridge in London on 3 November 2015.
