Not bad for a jockey who made the bold move to relocate from Ireland to Australia for greater opportunities over the jumps.

Having his first big feature ride for Godolphin trainer James Cummings, the Ballarat-based Allen had to use all his vigour to get Trekking ($10) to the front in the last few strides.

Gytrash ($3 favourite) raced a few lengths clear in the last 100m before Trekking charged down the centre of the track after sitting back on the rail in the $400,000 dash over 1200m.

Adelaide has been a happy hunting ground for Allen, with Trekking his fourth group 1 win in the city and second at this year's autumn carnival.

He also won the South Australian Derby on Russian Camelot a week earlier.

"He was tough and he had a super run, but the runner-up (Gytrash) gave a really good kick," Allen said in describing the Goodwood outcome.

"I thought when I got out that we were going to catch him but he (Gytrash) kept kicking.

"To my lad's credit, he really fought and kept kicking and put his head down on the line," he said.

Allen said as far he could remember he had only one previous ride for in what he described as a "poxy" maiden and he was appreciative of getting the opportunity on Trekking wearing some famous colours.

The Goodwood meeting ended a four-week stint in South Australia for Allen.

He spent the first two weeks after arriving from Victoria in self isolation after to meet COVID-19 restriction conditions.

He rode over three Saturdays and on returning home he will again stay in self isolation in keeping with Racing Victoria rules covering jockeys travelling from interstate.

This will also coincide with a suspension he received in the SA Derby.

Stewards outed him for careless riding for five SA meetings, which will extend until May 27.

UNBEATEN filly Macroura ($3.70 favourite) might yet earn a group 1 shot during the Brisbane winter carnival despite the challenges presented by coronavirus restrictions.

The Ciaron Maher and David Eustace-trained youngster made it three wins with an impressive victory in the listed Woodlands Stakes, 1100m, at Rosehill on Saturday.

The sprint is not a traditional launching pad to the JJ Atkins, 1400m, in Queensland, but stable representative Annabel Neasham says they can still make it work.

"That's going to be a bit of a jump to go from 1100 to 1400, but we will see how she comes through and consider it.

"She does switch off so she may well get that trip.

"We will just let the dust settle.

"She is an out-and-out two-year-old so we would probably like to get one more win on the board before putting her out for a spring campaign," Neasham said.
