LAVINIA Petrie has broken her second world record in two weeks at the Victorian Country Track and Field Championships on Friday.
The veteran long distance runner won the 70-74 years age group 3km at Llanberris Athletics Centre, crossing the line in just 13min 7.9 seconds.
The feat comes after Petrie broke the world record for the same age group half-marathon at the Oceania Masters athletics titles in Bendigo earlier this month, completing the 21.1km city track in 1 hour 37.38 minutes.
"I'm still a bit tired in the legs from the half marathon almost two weeks ago," Petrie said.
"I've been virtually running my whole life. It becomes a way of life."
Petrie, who hails from Kilsyth, said she had still not reached her full potential, however she is confident there is still plenty of fuel left in the tank.
"If I get niggle I get it tended to and I look after my body," she said.
The Ringwood Athletics Club member still holds the 50-54 women's ultra marathon (50km) world record at 3hr 43min.
Petrie will compete in the 10000m event tonight at 6.20pm.
