Sally Pearson's Commonwealth Games credentials will get the ideal workout when she tests her troublesome hamstring at the Diamond League meet in Games host city Glasgow at the weekend.
Olympic champion Pearson, the shining star of Australia's track and field team, has been carefully managing her recovery from a hamstring injury - pulling out of two recent major European meetings to avoid any undue risks.
In her 100m hurdles comeback race in Belgium a fortnight ago Pearson ran a sluggish 13.19 - well down on her usual standards - before shaving 0.3 seconds off that time the following weekend in Paris by running 12.89.
She will face a stern challenge on Saturday from Englishwoman Tiffany Porter, who ran 12.72 in Paris.
But a similar improvement this weekend in Glasgow, where she is hopeful of edging closer to her season best time of 12.59, would hold her in good stead to defend the gold she won in Delhi in 2010.
She then has one final chance to test herself in competition prior to the Games start on July 23 when she competes in Lucerne, Switzerland on July 15.
Pearson is currently still expected to chase the double of 100m hurdles and 100m flat at the Glasgow Games - as she did in Delhi - though that could change after discussion with her coaching group once the athletics team comes together later this month.
"If I can get this year right, no injuries, get another gold medal, and finish off with fast times at the end of the year, then I know I'm in good stead," said Pearson last week.
"I know I have that competitive drive still in me ... to become a better athlete, a faster athlete and become Commonwealth Games champion."
The Glasgow Diamond League meet will also be the second last chance for fellow gold medal prospects Dani Samuels and Alana Boyd to tune up for the Games.
Samuels enters the meet in great form, with a personal best throw of 67.99m this season, and she will face stiff competition this weekend when Croatia's Sandra Perkovic has the best credentials.
Boyd will contest the women's pole vault, having posted a season-best 4.65m jump in Germany last week.
Other Australians competing over the weekend include Collis Birmingham in the men's 5000m, Zoe Buckman in the women's 1500m and the men's 4x100m team.
