Button was joined in his race wave by British MotoGP 125cc rider, Bradley Smith, who recorded a total time of 2 hours, thirteen minutes and thirty six seconds.

The motorsport pairing exchanged some pre and post race banter, but it was Button who finished as the narrow victor after both men put in impressive performances.

Button commented, "I had to wake up at 4am to get here this morning and I loved it - it has been my best ever Sunday morning.  I enjoyed it today, it's such an amazing event, it's so big and it's great that triathlon is doing so well in the UK. I hope that its growth continues."

Of Bradley Smith, Button commented, "He did very well, he's a fit lad and so am I and it's great to show that at events like this. Our performance demonstrates that we do have to train hard to be an F1 driver or a MotoGP rider and that when we aren't racing, we aren't just at home sitting around and that we do have to be very fit in order to race at the level we do."
