"Pushing the Limits", co-written with sports journalist Warwick Green, is described by the publishers Penguin Books as "often funny, occasionally heartbreaking and always entertaining and engaging, this book is the true story of a true Australian champion who truly believes that anything is possible."

The 33-year-old Fearnley, who has acongenital disorder called sacral agenesis which prevented fetal development of certain parts of his lower spine and all of his sacrum, has won three Paralympic gold medals.

He won the T54 5,000 metres and marathon at Athens 2004 and then retained his marathon title at Beijing four years later.

At London 2012 he claimed silver in the 5,000m and bronze in the marathon, both behind great rival David Weir from Britain.

But to many Australians, Fearnley is better known as "the man who crawled Kokoda", single-file foot thoroughfare that runs 96 kilometres through the Owen Stanley Range in Papua New Guinea, location of the World War Two battle between Japanese and Australian forces in 1942.

"Along the way, Kurt shares the jubilation of winning as well as the depths of disappointment that come with competing at an elite level," the publicity material about the book claims.
