But those times finally fell on Saturday as the travelling nXtGen Track Team, basing themselves out at Oberon, set the Bathurst race alight.

Martin's mark of 16:41 for the five kilometre run had stood for more than three years - with only three other runners cracking the 17 minute barrier in that time - until Patrick Cantlon,16, went six seconds faster on Saturday.

The women's mark was handily beaten by 2018 Edgell Jog runner-up and fifth place overall finisher Belinda Martin, who went a whopping one minute and 23 seconds quicker than Zakrzewski's time to finish in 17:27.

Belinda Martin's time also shoots her straight to the top of the Bathurst parkrun age graded league, at 91.02 per cent.

The league factors in runners' ages to determine the overall top performers in the event. Next in tow is Kobe Stewart (88.18) and Ben Witney (86.02).

The record times were always going to be under threat when the Shire-based nXtGen Track Team arrived on the scene, according the Bathurst parkrun co-ordinator Stephen Jackson.

"We actually had two runners go under the old record and they were both from a club based out of the south of Sydney, nXtGen. They decided to come up from their camp at Oberon to have a go," he said.

"It was quite dramatic because the winner, Patrick, didn't have his parkrun barcode on him. We said 'It looks like you've got the record' but he had no barcode, though he was registered. When I said that his dad went racing to find his barcode for him."

Jackson said Belinda Martin looked to be producing a record breaking run from the outset of Saturday's event at Peace Park.

"Belinda Martin is well known in running circles. She smashed the female record. When she fronted for the run I thought there was a good chance of the record going," he said.

Bathurst runners Max Martinez, Nick North and Dean Windsor were all in the mix during Saturday's competitive edition.

In fact, North led the race at the turnaround point.

But from there Cantlon asserted his authority on the race in a pacing masterclass from the junior runner.

"Our local guys held their own. Max Martinez was eighth and ran a PB, which was brilliant. Even Nick North got smashed by this group and seeing that happen to him is pretty rare," Jackson said.

"It was still a bit smoky but the conditions were vastly improved from what they have been.

"Rumour has it the group might be back for the 7.30 event on New Years Day so we'll see how they go for that one."
