UK adventurer Sarah Outen is known for her amazing athletic ability and unending endurance. In 2009, she became the first and only woman (and the youngest person) to row solo across the Indian Ocean.

But that wasn’t quite enough for the ambitious 25-year-old. On April 1, she set off on her latest expedition that will take her from London, around the world, and back to London after two-and-a-half years of rowing, cycling and kayaking. A dangerous feat to say the least.

To provide coverage for such an event, Lloyd’s stepped in, issuing a $2 million insurance policy to be placed in the Lloyd’s market.

Jonathan Thomas, the Lloyd’s underwriter at Watkins syndicate who designed the policy, said: “Sarah has presented one of the most challenging underwriting propositions of any person I have quoted for personal accident and medical expenses coverage in the last quarter of a century.

Thomas also mentioned the risks posed by the duration of the trip, including uncertain food rations, muscle fatigue and the fact that she will be entirely alone.
