Olympic champion Sally Pearson is squarely in the sights of Melissa Breen as the Canberra sprinter prepares to reap the rewards of a three-year major overhaul of her running style.

Having completely remodelled her action after a disappointing 2010 Commonwealth Games campaign, Breen is poised to fly during the summer as she looks to defend her national 100m and 200m titles.

An exhausting, but confidence-building 11 races in four days as part of the Tasmanian gift circuit over the festive period, has the 22-year-old champing at the bit to test herself against Pearson.

The gold medallist in the women's 100 metres hurdles at the London Games is set to concentrate on the flat events in the domestic season to build speed.

There's also the possibility of a heavyweight sprint trifecta, with Athletics Australia keen to lure 200m gold medallist Allyson Felix to Melbourne for the World Challenge meet in April.

The American - who was also a part of her country's dominant 4x100m and 4x400m teams in London - trained in Sydney over the New Year break and would be a star-studded addition to the local circuit.

But it's the looming date with Pearson that has Breen fired up for the coming season.

''It's great having internationals, but it's great I've got Sal to run against,'' Breen said.

''I know she won't be competing as much domestically this season, but she's the best runner in the world and I get to practise against that in my own country.

''It'd be awesome if they [the international runners] came out, but I've still got the Olympic champ to race against week in, week out come March and April.''

Breen's goal is to qualify for the the 100m and 200m for this year's world championships in Russia in August, as well as defending her national titles in April.

She started the year in perfect fashion on the Tasmanian gift circuit, making every final and winning the 200m in Devonport off a one-metre handicap.

Breen has come a long way since bowing out in the semi-finals at the 2010 Commonwealth Games in New Delhi.

In conjunction with coach Matt Beckenham, she rebuilt her action from scratch, the move paying dividends as she lowered her 100m personal best to 11.27 seconds to earn a spot on the starting line in London.

She said Beckenham had told here ''2013 was the year … I'd be ready to step up after we changed things''.

''The model of Mel Breen isn't technically perfect yet, but it's a million times better. It kind of blows my mind a bit about what we've done, especially looking at old footage,'' Breen said.

''I'll put myself in the deep end and take on Sal and see what happens this year.''

She will fine-tune preparations for the season at an AACT Summer Series meet at AIS on January 19.
