With the world track and field championships set for Saturday in Berlin, many expect big thinks from several athletes.

All eyes will be on three-time Olympic champion Usain Bolt, the world-record holder in the 100 and 200 metres.

Bolt, who also led Jamaica to a world mark in the men's 4 x 100 relay, was the star of the 2008 Beijing Olympics and track observers think he can do even better in Berlin.

On the Canadian front, the nation's best shot at a medal could come in the form of hurdler Priscilla Lopes-Schliep. The Whitby, Ont., native shocked the field after winning the bronze medal in the women's 100 hurdles in Beijing.

Former world champion and Pickering, Ont., hurdler Perdita Felicien will also take part in event. Felicien won a silver at the 2007 worlds in Osaka, Japan.

So can Bolt run even faster than his incredible 9.69 time he posted during the Olympics?

Will Lopes-Schliep continue her ascent ? And who are some of the other athletes worth watching?
