Lauren Wells won the 400m hurdles final at the Australian Athletics Championships.

Canberra runner Emily Brichacek treated herself to a feast of sushi, Mexican food and ice-cream after booking her ticket to the Commonwealth Games on Sunday. 

But the 23-year-old says the ultimate reward for her successful return from injury would be winning a medal in Glasgow. 

Brichacek mastered a strong headwind at Melbourne's Lakeside Stadium to win the 5000 metres in a time of 15:52.65, ahead of New South Welshman Eloise Wellings (15.53.62).

Brichacek was overlooked for the London Olympics in 2012 despite posting a B-qualifier, and her world championship dream last year was ruined by a back injury. 

It makes the success she's enjoying now more sweet. 

"I already had the B-qualifier previously a couple of weeks ago in Sydney, today was just about getting the win,'' Brichacek said. 

"When you work towards something [in 2013] and realise it's not going to happen, it's pretty disappointing. 

"Before the race my coach said to me if you show up, it's going to set up my next four to six years.

"I was just super excited before this race. Having missed out so many times makes you appreciate when you're running and healthy.''

Asked if she is capable of winning a medal Brichacek said: "Definitely. To be honest I'm not even100 per cent sure of my competition at the moment, but the main thing is to concentrate on yourself.

"I think I'm in better shape this season, I definitely want to run a PB over there and get that experience at an international-level race.''

Meanwhile, Canberra 400 metres hurdler Lauren Wells is determined to translate her domestic success to the world stage after retaining her national title in a B-qualifer time of 56.76 seconds.

It is the seventh Australian championships win for Wells, equalling the record of the legendary Debbie Flintoff-King. 

Still only 25, Wells is desperate to secure her first medal at a major international event at the Commonwealth Games. 

"To even her amount of national titles is a great achievement, she's a role model for me,'' Wells said. 

"I feel I'm definitely on the road to making that big international impact. 

"It's great to do well in Australia, but you have to use that and go on and make your mark on the international scene. 

"I'm 25 now and I certainly feel the next three years is when I'm going to make the biggest impact.''

Other Canberrans to win their respective events and make the Commonwealth Games include Zoe Buckman (1500), Tim Driesen (hammer throw), while javelin thrower Kelsey-Lee Roberts is in a strong position for selection after winning silver. 

Australian 100-metres record holder Melissa Breen finished fifth in the 200 final, which was won by Ella Nelson. 

Sally Pearson can’t wait to step out of her comfort zone and take on many of the world’s fastest women when she doubles up at the Commonwealth Games.

The Olympic hurdles champion’s haul of national titles climbed to 13 on Sunday when she powered to victory in the 100 hurdles in 12.72 seconds, a day after winning the 100 metres sprint.

Pearson contested both events at the 2010 Games in Delhi and only a controversial false start in the flat race denied her two gold medals.

Pearson was one of 35 athletes to guarantee their Commonwealth Games spots at the trials, and up to 45 competitors will be officially named on Wednesday in a squad that could eventually number more than 100.
