Dunsborough adventure racer Jess Reynolds is about to complete her 40th sporting event on her 40th birthday as part of her 40-B4-40 project.
As part of the project, Ms Reynolds has been raising awareness and money for the Guillain Barre Syndrome Foundation of Australia after losing a close family friend to the rare neurological disorder.
Guillain Barre Syndrome is a condition in which the body's immune system attacks the peripheral nervous system.
In late 2016 Ms Reynolds' friend Chris McEncroe was diagnosed with Guillain-Barre Syndrome which turned his life upside down when he woke up unable to move on Christmas Eve.
Up until this time Mr McEncroe had been a healthy active 37-year-old husband and father of three young girls.
Seeing the devastating effect, physically, emotionally and financially, Guillain Barre Syndrome had on her friend's life, Ms Reynolds wanted to do something that would help them and also increase awareness of this terribly debilitating disorder.
In a true circle of events, the 2019 Collie Adventure Race will be both her first and final event as part of her project.
The annual adventure race is held on the second weekend each October and features a long course five-stage marathon relay for cyclists, canoeists, swimmers, mountain bike riders and runners.
A South32 Worsley Alumina spokesperson said the mining giant was excited to be a part of another event which encouraged visitors to visit Collie and marketed the town as a tourist destination.
"With such scenic waterways and bush land in and around Collie, the Adventure Race is a unique event that really showcases the natural environment," she said.
"New competitors, returning competitors and their family, friends and support crews are a great voice to promote Collie.
"We know that local service providers anticipate a busy weekend with so many extra visitors in town.
"We are proud to invest in the Collie Adventure Race and in turn help support local businesses."
