A competition with an incentive to improve health for individuals through exercising in the pool saw 13 participants achieve the mark.
The Wai Splash 100 Kilometre Challenge started with 25 participants. There were 22 last year and 19 the year before.
Starting on July 1 and finishing on September 30. participants were allowed to complete two hours in the pool per day swimming, walking or both to make the experience manageable and to dissuade them from going too hard in one session.
First to complete the 100km was John Edmonds, who took just 51 days – one more than the minimum possible. He attended the pool at 6am from Tuesdays to Thursdays, as well as weekend mornings, Monday nights and at lunchtime on Fridays, and in within two months, he’d clocked up a total of 120km.
