"This is my first time in this event and I only did it because David talked me into it," Luff said yesterday morning.
"He needed a support crew, so we have joined forces, with his wife driving our support wagon."
Luff has put in the legwork leading up to the event after taking up the sport three years ago after a long and successful rowing career.
Collins has been involved in top-level cycling for many years, although serious injury forced him out of the sport for some time. "I've only been back riding for the past six or seven months, although am still heavily involved in the sport through my job with Ron Cheatley and Cycle Sport NZ," he said.
Luff and Collins said they had coped well with the first three days, although both conceded it had been a daunting task with even more challenges ahead.
"After that first stage, I was thinking 'well, that's over', but then we are almost immediately faced with another tough leg in the afternoon. In group one, the pace is pretty hot and, even in my 60-69 age group, there are some very sharp riders, so it's not easy," Luff said.
His ability to ride on or somewhere near that pace had Luff in 30th place overall after the Hunterville to Wanganui stage that finished in Eastown Rd on Tuesday afternoon. "It's funny, my race number is 30 and I'm in 30th place. But it's that pace in the group that has dragged me up."
In contrast ,Collins was in 58th spot overall as he set off for Kakatahi yesterday, although ironically his placing also matched his bib number two days before when he was in 62nd spot.
"This is a very challenging event, especially the hills - and there are plenty of them," Collins said.
This year's event raises money for Think - the head injury network for Kiwis.
