Watch as 2X Ironman World Champ Chrissie Wellington takes on 2X Xterra World Champ Julie Dibens at the 2009 5430 Long Course Triathlon in Boulder, Colorado.

The weather was perfect as the gun sounded the start of the 5430 Long Course (half Ironman) triathlon. The race was on between the two Brits who both train in Boulder.

Chrissie Wellington has won the Kona Ironman World Championship two times in a row.

But Julie Dibens has won the Xterra World Championships an equal amount of times.

Did an epic race between two of the best women in the world mark 8.9.09...or is it just another race day in the life of Chrissie Wellington?

Who wins?
