Multiple major medal winner Jared Tallent will continue to focus on the 50-kilometre walk at August's world championships despite claiming a sixth successive Australian 20km title.
The Canberran won the 20km event in Hobart on Sunday in one hour, 22 minutes and 10 seconds, well inside the A qualifying standard for the world titles in Moscow.
But, having won three minor medals at the 2008 and 2012 Olympics and bronze in the 50km race at the 2011 world championships in Daegu, Tallent has decided his best chance of claiming gold at a major championships is to target the longer event this year.
''For me, 2013 is centred around the 50km event at the world championships,'' he said.
''I want a gold medal to sit alongside the silver and bronzes that I have won and, by focusing in on a single event, I am confident that could be a possibility.
''The program in Moscow makes it very hard to do both.
''My wife Claire and I are making some pretty big changes this year by moving to Adelaide soon and also with her taking over as my coach. It's been a good move for me.''
Dane Bird-Smith and Luke Adams finished second and third in Hobart respectively, both also going under the A standard for the world championships.
The standard was also high in the women's race, with winner Tanya Holliday (1:34:32) booking an automatic spot on the world championships team and second placegetter Cheryl Webb also bettering the qualifying mark.
''I'm happy to have won, but I am really disappointed with the time,'' Holliday said. ''At least I now know that I will be in the team for world championships but, if I want to be in the mix, I need to move quicker.'' AAP
