Fours years ago Levin man Mike Ball set out to do an Ironman. There was fly in the ointment though. He couldn't swim.
"I couldn't swim. I would sink like a stone," he said. Determined to learn, he took lessons.
It took months before he was able to swim an entire length of the Horowhenua Aquatic Centre, but gradually he improved and before long he could swim two lengths, then five, then a kilometre.
Now he has completed five Ironman events, a gruelling contest made up of a 3.8km swim, a 180km bike ride and finished off with a 42.2km run.
The 56 year old moved from England to New Zealand in 2006. He said there wasn't much emphasis on learning to swim as a child.
