Kiwi triathletes Cameron Brown and Jo Lawn go into this weekend's Ironman World Championships in Hawaii as the most experienced veterans in the field of the sport's toughest test.
They're each competing in their 12th straight time at the world championships, a feat not matched by any other in the stellar field.
For compatriot Sam Warriner, even though the oldest of the kiwi trio at 40, it will be her first time in one of the world's iconic sporting tests.
Warriner, the former Olympic distance World Cup champion and world championship medallist, only moved up to the full Ironman distance in earnest this year with a debut victory in Ironman New Zealand over world champion Australian Mirinda Carfrae and Lawn.
Brown, 39 and Lawn 38, know that this could be their last time in Hawaii, although both have been in impressive form this season.
Brown says it's probably the last throw of the dice for him - he's a four-time podium finisher, but never quite reached the top.
Lawn has been in the top 10 on six occasions and twice was just one place off the podium.
