Chrissie Wellington broke the world record for the Iron-distance triathlon today (18 July) in Roth, Germany. She recorded a time of 8hours 19:13 to beat her own previous mark by 12 minutes and 46 seconds, and won the Challenge Roth event by over half an hour from Australia’s Rebecca Keat.

Wellington, 33, is the reigning World Ironman Champion, having won the title for the third year in a row in Hawaii last October. She was recognised in the Queen’s Birthday honours list last month with an MBE and her performance today represented her ninth win from nine Iron-distance starts. She obliterated her 2009 world record of 8:31:59, which was also set in Roth.

Wellington’s marathon time of 2:48:54 after completing a 3800m swim and record breaking 112mile bike ride was the fastest ever achieved in an iron-distance triathlon.

She said: “I’m overjoyed, yet overwhelmed. Hopefully I have redefined the limits for myself, and for others, of what is possible. It has been one of the best days of my life. Challenge Roth epitomises everything that is great about triathlon.”
