About 30 cardiologists and health professionals from around the country swapped white coats for red jerseys for the full 2010 Great Ride for Heart fundraiser, with other medics and cycling enthusiasts joining in for different stages.
Together they raised more than $1.1 million.
Participants in the full ride set off from Cape Reinga on February 1.
They promoted awareness of heart disease, New Zealand's greatest killer, while they travelled, .
Cardiologist Dr Gerard Wilkins, of Dunedin, said the medics had been setting an example by exercising, and money raised would fund research into why an increasing number of New Zealanders in their 30s and 40s were presenting with heart conditions.
The riders had cycled 192km from Twizel, over the Lindis Pass to Wanaka, then over the Crown Range, to stay overnight on Saturday at Millbrook - one of the sponsors - near Arrowtown, when the Queenstown Times caught up with them.
"This is the 13th day of pedalling, I'm definitely feeling my age," Dr Wilkins said.
"It's a great group of people, morale is fantastic.
"We've been blessed with the weather."
"There's been big support of the cause and the money keeps coming through."
Dr Wilkins said the group was averaging one or two punctures every day.
There had been no injuries other than sore bottoms, backs and strained tendons.
"Steve Dyet owns Browns Avanti Plus and he's our cycling mechanic.
"He is utterly invaluable and he's constantly fixing."
The team made the final 220km push to Stirling Pt, in Bluff, on Sunday, with the first cyclists arriving about 5pm.
Former prime minister and foundation patron Dame Jenny Shipley, of Auckland, said the ride had given the professionals a rare opportunity to re-connect, as many had studied together.
The experience had also enabled them to share ideas about cardiology.
"It's by far the biggest fundraiser the heart foundation has run," she said.
"My cardiologist, Mark Simmonds, and one of the specialists, Andrew Aitken, who looked after me when I had my heart attack in 2000, are on this ride and I find that inspirational."
