Especially after main sponsor spokesman (and competitor) Simon Tremain posted a Facebook challenge to them - given they were already aboard as co-sponsors.
Mr Tremain also challenged another co-sponsor, Greenmeadows New World, to go the extra step (and paddle and pedal) and get a team together.
Five days after posting the challenge the New World crew said yep, they'd have a crack at it and three days after that the PKF athletes also accepted the challenge.
"We've got two teams in this so some very good strategy is going to be happening," Mr Lines said.
"We're up and running ... and cycling and paddling, and we're ready. We love a good challenge."
Mr Lines said after a break from competing the time was right for the PKF teams to step back up to the mark - and show Mr Tremain how good they were.
"We're ready. I wonder if he is," he said, adding that much of the preparation fun had centred on the video clips company teams had been posting on the event's Facebook page as response to Mr Tremain's "are you up for it?" takes.
Organised in association with Triathlon Hawke's Bay and a string of co-sponsors, the event is staged to be both competitive and fun, where individuals and teams can challenge each other as well as simply enjoy just getting together.
This year's event will see the addition of stand-up paddling (SUP) for one of the three classes.
Competitors in the three-person teams can take on the 1300m SUP course in the Pandora waters as well as the 5km run and 20km cycle leg.
The other classes are for swimming (600m) and kayaking (1700m) alongside the running and cycling.
Tremain Real Estate marketing and events co-ordinator Luke Jackson said registrations, which had now closed, showed the event would easily be on a par with last year's big turnout.
He said the number of teams was in "the high 200s" and with many of them sharing their ambitions and challenges on Facebook during the build-up it was set to be "great fun".
"It's great to see it all happening and hopefully the weather will be good to us - fingers crossed."
The MetService long-range forecast for Napier on Sunday is for some overnight showers to clear and southerly breezes dying out - with sunshine and cloud mixed together for a high of 20C.
"Bring it on," Mr Lines said.
