The Sovereign Tri Tinman at Mount Maunganui tomorrow morning is expected to attract a bumper field of more than 700 participants across all four events.
Tinman offers race distances for all abilities and backgrounds, from beginners to youth to serious age groupers and elites.
One of the traditional openers to the season, the Tinman has a history that dates back more than 25 years and boasts some of the greatest names in the sport on the honours role, with Hamish Carter, Cameron Brown, Walter Thorburn, Graham O'Grady, Karyn Ballance, Heidi Alexander and Nicole Cope all having won the event that takes in a run course around the base of The Mount before heading to the finish line at Pilot Bay.
A familiar name on the start line is former world champion Sam Warriner.
"This year has been a bit of a roller coaster for me. It started with a hamstring injury that first caught me at Tinman last year. Unfortunately it took longer to rehab than I'd hoped and wrote off all of last summer. This past winter we managed to get pregnant for our second child and Lola was all excited about being a big sister. I had made my mind up that I wouldn't race anymore and would focus on being a mum and coach so I let the training go and just nested to be honest. Unfortunately though September was a roller coaster, I miscarried at 14 weeks which knocked me and had to go into hospital.
