Marathon runner Brad Luiten, pictured here after claiming his first world record for running on crutches, has captured another.

A New Zealand marathon runner has achieved the unthinkable by finishing 237 holes of golf in 12 hours - and earning himself a Guinness world record in the process.

Brad Luiten, a national-class runner, smashed, putted and drove his way to the record, reaching his golf goal on Monday evening.

Striking while the six-iron was hot, he launched his quest at 7:40am at the Helensville Golf Club before finishing it 12 hours later, TV One reported.

Luiten shattered the previous record, 221 holes, with almost an entire course's worth of holes to spare.

He beat the record of Canadian Scott Holland, who managed 221 holes at Fairmont Banff Springs Golf Course in Banff, Alberta, Canada, in 2005.

Luiten's motives did not just include personal glory.

He was inspired to take a swing at the record in order to raise money for Bowel Cancer NZ, and commemorate his friend, Stephen Gove, a prominent football player-coach, who died from the illness in June last year.

New Zealand has one of the world's highest rates of bowel cancer, is currently one of the worst countries in which to contract it, with about 100 deaths per month.

With Bowel Cancer NZ only retaining two part-time staff, Luiten is hoping to raise awareness - and funding.

"A friend passed away last year from bowel cancer, it's all about that today" he told TV One.

In January last year, Luiten hopped his way to Guinness World Record, becoming the fastest man to run 10 kilometres on crutches while raising money for Starship children's hospital.

The golf experience also honed Luiten's marathon running prowess.

In total, he ran a combined 100km during the event .

But Luiten has made good on clocking the unimaginably taxing record.

"He's always up for a challenge," his wife Nina said.
