Grandma among 1st Women to Row around Britain

A 50-year-old wheelchair-bound former U.S. marine and three teammates have become the first women to row nonstop around mainland Britain after completing the 2,000-mile journey.

Amateur rowers Belinda Kirk, Laura Thomasson, Beverley Ashton and Angela Madsen reached London's Tower Bridge on Friday to finish the trip in 51 days, 16 hours, 42 minutes.

Madsen is a wheelchair-bound former U.S. marine from Long Beach, Calif. She has rowed the Atlantic and Indian oceans but says Britain "presented the most challenging and unpredictable weather patterns."

The 50-year-old grandmother broke her finger setting off a flare but carried on with a strapped hand.

The quartet started the race against a men's team June 1, but the men gave up after less than two weeks.
