Her competitors were hoping to get close to the Canberra sprinter but were left watching in awe as she crossed the line half a second before the silver medallist at the Australian Institute of Sport..

For the last 20m Breen took her foot off the accelerator and relaxed, already turning her attention to today's 100m final.

She was hoping for another blistering time today but said she would settle for achieving her goal of two gold medals.

''Maybe I could run another record tomorrow, it just depends on the conditions,'' Breen said. ''I don't feel like I have to go and run another 11.33[sec] or an 11.2. I'm still young and I've got a lot of time to improve and plenty more years in the sport.

''The 200m is done now and on the second day I can really enjoy my pet event and just lap it all up.''

Just before her 200m start her record in the under-15 100m, which was set three years ago in Melbourne, was broken and Breen was determined not to be outdone.

She was first out of the blocks and never headed, collecting her first gold medal of the meet in 23.52sec.

But the 18-year-old has her sights set on claiming the 100m crown which slipped from her grasp at the 2005 Games.

She set the record in the heats in Melbourne but had to settle for a silver medal in the final.

''I was warming up and my 100m record was broken so I thought I better break another one, it's lovely to do that,'' Breen said.

''I'm glad I've done the 200m now and I love the 100m, it's very corny, but I'm proud of myself and it's great to do another PB.

''The nerves were there a little bit before I started but now they're out and I'm ready to go again and hopefully things go well in the 100m.''

Breen became the fastest Australian woman over 100m this year and ran the second fastest time, 11.33, by an Australian junior ever last month.

She has been tagged as a future Olympic medallist but she's not feeling the pressure.

Instead she likes the attention and said she was determined to live up to all expectations.

''It's something different and exciting for me and I guess it's pressure but I expect that,'' she said.

''I've been running well in training but races are a different thing and if there is any pressure it's trying to put practise on to the track on the day.''
