Nine days, 250 kilometres, 1000 sand dunes - Glenfield's Surayez Rahman has a hell of an adventure ahead of him.
The Suncorp executive manager is about to take off on the journey of a lifetime for the 2019 Simpson Desert Challenge.
The challenge raises money and awareness for charity Youngcare, which is working hard to improve the lives of young people with high care needs.
"When the opportunity came up for me to be involved in this challenge, I couldn't say no," Mr Rahman said.
"There are too many young people living in aged care because there isn't anywhere that caters for their needs.
"I had leukaemia as a child so I know what it's like to feel out of place - I've experienced that feeling of distance from everyone else."
Mr Rahman hopes to raise more than $60,000 to assist Youngcare as one of the 14 participants taking on the Simpson Desert Challenge this year.
The 33-year-old has been training for the past six months to build up his stamina and endurance.
"I work in the city so about once a week I get off the train at Wolli Creek and walk 15-20 kilometres to the office," he said.
"I've also been practising long distances on beaches - walking on sand is very different from walking on concrete."
Mr Rahman said he'd had a mixed reaction to the trek from his family.
"They're really proud of me and really supportive but at the same time it's like, 'are you insane?'," he said.
Mr Rahman said he was preparing for the harsh desert conditions.
"I've been to the desert in Africa, but I haven't stayed overnight," he said.
"The reason we do the trek in May and June is because the weather is a bit better.
"But it will still be about 35 degrees in the day and down to five degrees at night - and we won't have any toilets, showers, beds or anything for the whole nine days."
There are 12,000 young Australians with high needs living in accommodation unsuitable to their situations.
Money raised on the trek will help provide accessible and age-appropriate living spaces for these people.
