South Yunderup local Paula Prynne proved age is no barrier when she conquered a grueling 600-kilometre ride as part of the South West Bike Trek earlier this month.
The 81-year-old was one of more than 20 riders who tackled the six-day trek from Perth to Augusta, which raises funds for the Children's Leukaemia and Cancer Research Foundation.

The group made stops at Fairbridge, Harvey, Eaton and Margaret River before finally ending their journey in Augusta, riding 100kms each day.
Paula faced a couple of minor hurdles throughout the challenge, including a small collision with a fellow rider early in the piece as well as a flat tyre at Fairbridge.
Persistent headwinds also made the ride more difficult, and on the final day fellow riders pitched in to give her a windbreak reprieve.
But nothing could stop Paula from reaching her goal, as she eventually made her way past the finish line.
"It was a wonderful experience with a lot of fun and laughs along the way," she said.
"Being the oldest cyclist with only three years' cycling experience I felt privileged to be allowed to take part."
Event organiser Eric Maddock was full of praise for Paula's efforts.
"She's a pretty awesome lady," he said.
"Even in the face of some tough winds and just how challenging the ride can be overall, she never showed any signs of slowing down or giving up.
"It's an amazing achievement."
While a final figure is yet to be determined, Mr Maddock said the fundraising total had already surpassed $15,000 for this year's event.
"To raise that much money for a worthy cause is really special," he said.
"This is our 18th year and over that time we've raised more than $800,000."
Cyclists in the trek were supported by community members along the way, including the students at Harvey Primary School, who joined them for a portion of the ride while also raising $600 themselves.
