Dylan Armstrong of Kamloops, B.C. earned the world season's best throw of 22.21 metres at the Canadian championships in June. He also leads the international Diamond Race, well ahead of competitors from the United States and Poland, all of whom he has defeated this season. If he wins, he will give Canada its first gold medal in the shot put at a world championship.
Priscilla Lopes- Schliep of Scarborough, Ont., won't be going to South Korea, because she's expecting a baby on Sept. 20. But the former No. 1 world hurdler at 100-metres is intent on returning in time to make it onto the podium of the 2012 Olympics in London next year. Lopes-Schliep won a bronze medal at the Beijing Games and a silver at the 2009 world championships.
Perdita Felicien of Pickering, Ont., is gunning for the one medal that has eluded her in her long career: an Olympic one. The 2003 world champion and 2007 world silver medalist has had some minor injuries this season and a switch to a new training environment but knows the ropes.
Phylicia George of Markham, Ont., is one of five top female hurdlers in Canada and one of the new faces. George has risen through the ranks quickly this season and defeated Felicien at the National Track League's final stop in Toronto.
Jessica Zelinka of Calgary took 2009 off to have a baby after finishing fifth at the Beijing Olympics, but she's back in top form. Her plan is to boost her best score to 6,500 points in the heptathlon, and if she does, she has a shot to be on the podium in South Korea.
