Rebekah Keat, Burleigh Hea QL AUS - 09:56:01

It's really not quite fair to see her here. But at the time we didn't know why.
Earlier when Chrissie Wellington flatted she didn't have tech support and had to make her own repairs. In the process her CO2 cartridge misfired and the tire didn't properly inflate.
It was Rebekah Keat who stopped and gave Chrissie a spare cartridge! Eventually Chrissie repassed Rebekah and went on to defend her Ironman title.
