KILSYTH'S Lavinia Petrie broke a world record at Sunday's running of the half-marathon on the final day of the Oceania Masters athletics titles in Bendigo.
Petrie raced the 21.1km around Bendigo's streets in a time of 1 hour 37.38 minutes.
The 70-years-young athlete shattered the previous world mark of 1:42.
Petrie's time is to be ratified and therefore is a pending world record.
The record-breaking feat and gold medal capped an outstanding performance by Petrie across many days of the nine-day championships.
"To have broken the world record is an unbelievable feeling," Petrie said from near the finish line in Rosalind Park.
"This was a fantastic course to race on.
"It was well-marked, well-marshalled and there were lots of competitors."
This week's campaign was Petrie's third at Oceania Masters level. She won gold in the 8km cross-country, 5km, 1500m, 800m.
The Ringwood AC and Victoria Masters member earned a Special Recognition award for highest percentage of Masters athletes at 101.
Fastest of the Masters in the Bendigo half-marathon were Paul Marsh, 1:15.57, and Lisa Davis, 1:28.
Bendigo athletes to win their class in the half-marathon were Darren Hartland, 35-39 years in 1:24.15; and Charles Chambers, 60-64 years in 1:24.18.
The Masters finale included an open half-marathon won by Eaglehawk's Luke Preston in 1 hour 15.37 minutes.
