Meet Mark Gibbens, a 50 year old Australian Registered Nurse and Ultra Distance Walker.
In 2006, after living in Japan for eight years, he was determined to repay the kindness of the Japanese people. So with the support of the Japanese Medical Association he walked the length of Japan (3000km) from Sada Misaki to Sato Misaki with the simple message of "No Smoking Is Love", in the process generating millions of dollars of health promotion advertising.
Building on this success, in 2009 with the support of Australian Rotary Health and individual Rotary Clubs across the country, he walked 5200km solo across Australia, raising $25,000 for Children's Cancer Research.
His next endeavour - walking from San Francisco to New York - 5000km in 50 days, to raise money for Red Cross water and sanitation projects. His plan is to leave from Lincoln Park, San Francisco on Saturday the 24th of August 2013 and arrive in Times Square, New York on Saturday the 12th of October 2013.
