An Australian veterinarian has completed a solo crossing of Antarctica with a custom-built pink sled modelled on his wife’s breasts.

Gold Coast-based Geoff Wilson, 43, is the first Australian to cross Antarctica coast to coast, alone and unsupported.His journey of 3,428.53km took 53 days of kiting, skiing and trekking and is the fastest anyone has traversed the continent this way.He carried supplies for his expedition, which aimed to promote breast cancer awareness and raise funds for the McGrath Foundation, on his distinctive sled, made from an upscale mould of his wife's breasts."Mentally they were a companion," he said on Thursday.Wilson said it was the cancer experience of a close friend, journalist Kate Carlyle, that inspired him."There were multiple times when I hit a dead end and felt that I physically couldn't go on."Katie has had to walk this road, and the road's not over yet."The president and co-founder of the McGrath Foundation, cricketer Glenn McGrath, said Wilson's determination to support families touched by breast cancer was symbolic of the support he and his late wife Jane received."I think it's incredible. I think that's what life is about, to see that love and support," he said. "You can go through things by yourself but you're never alone, like Geoff was on the ice."Prime minister Tony Abbott hailed Wilson's achievement as an extraordinary feat in Australia's Antarctic history."You didn't do it for personal glory, you did it for a cause. On behalf of every Australian I congratulate you on this extraordinary, amazing effort," he said in a video message.(theguardian.com)ANN.Az
