The amazing life story of Britain's world conquering triathlete, Chrissie Wellington. Chrissie Wellington is the world's No 1 female Ironman triathlete, the current quadruple World Champion and World Record holder. In 2009 she was voted 'Sunday Times Sportswoman of the Year' and in 2010 was awarded the MBE. She is the undefeated champion of Triathlon, having won nine Ironman titles from nine races. Her World Record setting race time of 8:19:13 at Quelle Roth Germany in 2010 slashed over 14 minutes from the previous record and where she was only beaten by six men. Chrissie has displayed unprecedented levels of stamina, strength and competitiveness in becoming Ironman World Champion in only her second event at Ironman level. Her victory in Kona, Hawaii in 2007 finishing in 9:08:45 - five minutes ahead of her nearest rival - was described as the 'biggest upset in Ironman history' and 'a remarkable feat, deemed to be near impossible task for any athlete racing as a rookie at their first Ironman World Championships'. She defended her World title in Hawaii in 2008 and again in 2009 and won back her title in 2011 after having to withdraw from the 2010 race due to illness.

This is the remarkable story of how a Norfolk girl - a 'sporty kid, swimming, playing hockey, running, but never excelling and always more interested in the social side of the sports scene' - became a world champion. Chrissie Wellington is the world-record holder for ironman-distance triathlon, and she remains undefeated over the Ironman distance.
