Over the years, more than a few former rugby players have attempted Ironman Wales in Tenby. There's something about the gruelling challenge of a lengthy swim, a hefty bike ride and a mere marathon to finish that appeals to the competitor.
Shane Williams, Ian Gough, Andy Moore and Colin Stephens are just a handful who have pushed themselves to the limits in Pembrokeshire. Yet only one can claim to have completed each of the 10 brutal races to date.
Paul Arnold is that man. He and his wife Jayne, the woman who first got him into doing triathlons, are in a very exclusive club. Just 10 people have completed all 10 Ironman Wales events and they account for two of that list.
