London run has Buckman on track for Moscow Zoe Buckman ran a solid fourth in the Diamond League 1500m when returning to the London Olympic stadium on Friday and is now dreaming of a possible podium at next month's world championships in Moscow. Buckman was full of confidence at the east London venue where she set a PB of 4:05.03 a year ago to just miss the final at the Games. "I thought if I can keep up in the Olympics then I can keep up with this bunch," the 24-year-old told AAP on Friday. Buckman ran aggressively at the front until fading in the final 50 metres. She wasted energy with a slightly choppy stride meaning there's room for improvement ahead of the worlds. "I've got the speed in my legs and I've got the aerobic fitness behind me," the Australian said. I'm just as competitive as the next person going in. Buckman insists she has a good chance of making the world championship final in mid-August. Then she can dream of a podium spot. The 1500m is a tactical event so it (a medal) is possible providing that I run smart and make it through to that final. Friday's race was won by Kenya's Mary Kuria in 4:08.77. Buckman ran 4:09.23. Jackie Areson is also heading to Moscow to compete for Australia. She set an A qualifying mark in the 5000m at the Diamond League meet in Paris earlier in July. The dual US and Australian citizen previously competed for America. Areson was born in Hong Kong and moved to the US when 10 but her mother is Australian. The 25-year-old is excited to be heading to the Australian team training camp on Sunday and then the worlds. "I hope everybody is excited and doesn't think of it negatively - that I'm just an American trying to switch," she told AAP on Friday. I consider myself more Australian than American because I was raised by my huge Australian family. Ever since I left Hong Kong I always wanted to move to Australia. I see myself going back there in the next couple of years. Areson ran a disappointing 3000m at the Anniversary Games finishing 15th in 9:08.02. Shannon Rowbury from the US won in 8:41.46. "I've had trouble with being really up and then really down," the Aussie said. I'm trying to get more consistent - it's one of the things I have to get better at. Kelly Hetherington was also disappointed with her 9th place in the 800m on Friday although her time of 2.02.22 was only a second slower than her PB. American Brenda Martinez won in 1:58.19. The Australian, 24, missed the 2012 Games due to a bacterial infection. "I didn't think the pace would be that quick so I just went with it," Hetherington said. I thought 'What the heck' and then struggled. Of the other Australians Brandon Starc cleared 2.16 on his first attempt in the high jump but then failed at 2.20. Lauren Boden came last in the 400m hurdles in 55.93. Olympic and world champion Sally Pearson hopes to find some form in the 100m hurdles on Saturday ahead of attempting to defend her title in Moscow.
