The latest chapter in Kathy Watt's colourful career will be written on Wednesday as she chases a spot at next month's world road cycling championships in Canada.

Watt must win the 30km individual time trial at the national club championships on the Sunshine Coast on Wednesday to qualify for the event in Hamilton, Ontario.

The 1992 Olympic gold medallist announced her comeback to cycling in June following a three-year lay-off from the sport.

Coach and partner Carey Hall said the Victorian was desperate to make the world championships and find out if she was on track for next year's Athens Olympics.

He said the Barcelona Olympic road race champion was focusing on the individual time trial this year but would consider a return to the track in the form of the 3,000m individual pursuit next year, depending on results.

Australia's best female road cyclists will not be competing in the race because of overseas commitments during the northern cycling season.

The race doubles as the Oceania road championship which allows the winner's country a berth in the world championships starting October 6.

"One step is to win here tomorrow and I guess the second step is to ride the world championship in four weeks in Canada," he said.

Hall said age was not a factor for the 38-year-old as long as the four-time Commonwealth Games gold medallist still had the hunger for the sport.

"At the end of the day Kathy will show if it will work, people cycling in their late thirties can still win world championships," he said.
