Four British women have rowed 8,500 miles across the Pacific Ocean from San Francisco to Cairns, Australia in an inspiring adventure to raise money for U-K charities. They are Laura Penhaul, Natalia Cohen, Emma Mitchell and Meg Dyos and they must be friends. They spent nine months on a boat, rowing two-hour shifts all day, seven days a week, without a toilet and with only an hour-and-a-half nap at a time.:Lynda Kinkade reports.
