Sam Clark knows all about hurting himself but freely admits this weekend's Mount Monster may just take him into a new realm of pain.
The Whakatane multisport star - who won his second Coast to Coast title in fearless style earlier this year - has added an intriguing element to New Zealand's biggest surf lifesaving endurance race.
While the 5km beach run along the Mount Maunganui coast, the spectacular 1500m swim leg which includes a jump off Moturiki Island's blowhole and the 12km ski leg to Omanu and back hold no fears for Clark, he's conscious of his inexperience with the final 6km board paddle bringing him home.
"I can see three out of the four disciplines going pretty well," the 27-year-old said.
"I've been doing a lot of swimming over the past six months, focusing on ironman, so I know I'll be handy in that respect. I've done a lot of running over the years too and I've been paddling since I was about 10. The only thing I haven't done too much of is the board paddling. I've been out twice and my shoulders feel like they're going to explode - I'll just go hell-for-leather and hopefully the first three disciplines will help me get a decent result."
