Canberra para-cyclist Sue Powell has confirmed she is aiming for her Paralympic swansong in Rio after extending her remarkable unbeaten record at national championships on Saturday.
The 48-year-old (28:44.3) beat New South Welshman (Alexandra Green) by eight seconds in the C4 time trial (18.5km) in South Australia to secure her 29th national crown.
Powell is yet to lose at national level on both the track and the road, and will now focus on the world championships in Italy from March 17-20.
The Paralympic cycling team is yet to be confirmed for Rio but Powell is hopeful she will be selected and have a chance to add to her gold and silver medals at London in the individual pursuit and time trial respectively.
"That [Rio] will be my last one [Olympics]," she said.
"I'll be 49 at Rio if I get selected and it'll be tough, but if I can do a PB [personal best] and hopefully get a medal or two, it'd be great but I have to get there first.
"There's three quite good girls in my category so it was pretty competitive.
Powell believes her remarkable unbeaten national championships record will be broken in Sunday's road race on a "pretty hilly" course.
"Tomorrow might change things, I'm not much of a hill climber," she said.
"Quite a few people are preparing for the track world champs and the team goes into camp on Monday.
"It [national championships] is a good chance for a hitout but perhaps not where we're targeting right now."
