They called him 'Hands of Stone'. In his own words, and for the first time, Roberto Duran tells his unbelievable story in I Am Duran: The Autobiography of Robert Duran.

From the mean streets of Panama to the bright lights of Las Vegas, blazing a trail through the golden decade of boxing, Duran, in unflinching form, dispels myths and lays bare the cost of conquering the world. He also returns to the debacle that entered sporting folklore during his rematch with Sugar Ray Leonard, when he uttered the infamous words 'no mas' - no more.

Starting life in abject poverty as the illegitimate son of a serving US soldier, Duran quickly realized that his fists could both protect him on the streets and put food on the table. His reputation in and out of the ring travelled the corridors of boxing power on the day, for a bet, he knocked down a horse with a single punch.

From his stunning debut in New York to the glorious defeat of Sugar Ray Leonard, the world titles and the chaos that ensued after the No Mas encounter, Duran's explosive life in the ring was matched only by the volatility outside of it, as he lurched from kingmaker to bankruptcy, before the ultimate ending of a bloody comeback and, finally, redemption.
