Chrissie Wellington defiant after accident

Norfolk triathlete Chrissie Wellington is adamant she will be fit to compete for her fourth Ironman world title, despite a bike training fall.

The 34-year-old published photos of her bruised and grazed legs and arms on social networking site Twitter  .

Wellington added: "The body is capable of amazing things. I WILL be on the start line."

The Ironman World Championships, a 2.4-mile swim, 112-mile cycle and 26.2-mile run, are in Kona, Hawaii on 8 October.

"Long story short: Front flat tyre, cornered, came off, nothing broken, very battered, bruised and bloody. But still full of fight," she posted.

She continued: "Life throws you curve balls. The key is to bounce those balls right back. Pain. It's a brain game right?!"

Wellington, from Feltwell, missed last year's event through illness  after winning the title in the three previous years.

She has been in outstanding form in 2011, knocking a minute off her own world record, clocking a time of eight hours, 18 minutes and 13 seconds in Germany two months ago.
