Omanu's Cory Taylor and Midway's Max Beattie resume their ironman rivalry in Mount Maunganui tomorrow, although they'd be well advised to keep an eye on a rising tide of talent behind them.
Taylor heads into Saturday's Mount Monster surf lifesaving endurance race as defending champion, having beaten Beattie by nearly five minutes in last year's inaugural 25km classic.
It kick-started a magnificent year for the Gold Coast-based Gisborne star, who went on to win his first national ironman title and help New Zealand take the world championships in France.
"It was cool to win the first one because I didn't know what to expect going into it and it was a new, exciting experience which New Zealand hadn't seen before," Taylor said.
A strong local contingent could be the two stars' biggest challengers, led by Mount Maunganui's Sam Shergold (fourth last year) and Whangamata's Bjorn Battaerd.
Some ultra-talented teenagers are lining up too, including Papamoa pair Mason Bryant and Andrew Trembath, Omanu's New Zealand under-16 ironman champion Sam Pasley and Mount Maunganui quartet Hamish Miller, Kane Sefton, Daniel Barron and Isaac Marshall.
"Not only is it a 25km stretch of incredibly beautiful coastline but it's a event with great competitors," Beattie, the 2012 and 2013 New Zealand ironman champion, said.
"Just things like jumping off that rock at the end of Moturiki Island - it's picturesque and there's no place in the world like it and to be able to race here is something special."
The women's field has had a late injection of Olympic class, with kayaking star Teneale Hatton signing up to race to get valuable cross-training for her flat-water pursuit.
She will link with a strong Piha contingent, with club coach and fellow 2012 Olympian Steve Ferguson having raced the inaugural Mount Monster last year.
Hatton's teammate, Kirsty Wannan, shapes as one of the women's favourites, alongside the Mount's Katie Wilson, who was second last year.
The forecast is looking ideal, with a 1m swell and light northerlies tipped.
