More than 5000 kilometres over 10 days across some of Australia's most rugged terrain.
And the journey must be in a car worth less than $1000.
What might sound like a nightmare for some has Falcon couple Greg Butcher and Annette Turner eager to hit the road.
Taking part in this year's S...box Rally, the motor sport mad pair will drive from Perth's Optus Stadium to Centennial Park in Sydney for the largest national, independently-run Cancer Council fundraiser.
The event, which will celebrate it's 10th anniversary this year, has raised more than $17 million for cancer research since it first started.
Mr Butcher and Ms Turner said they joined the fight as a "fun way to help out" after watching family and friends "suffer from the s..t disease".
Their team name, ForDad, is dedicated to Mr Butcher's father, who passed away two days before the couple signed up for the rally.
The car they hope will make the distance is a Ford Falcon 'Shaggin Waggin' they bought for $300.
Mr Butcher said it was an "absolute bargain".
"We've spent maybe another $200 on it adding our own little touches to it," he said.
"Our friend donated wheels and tyres for it because you have to take a couple of spares.
"If it dies on the way, it is our responsibility to get rid of it and we have to have a farewell.
"She'll be right, it's a Ford!"
Mr Butcher said they are looking forward to the dress up days, activities each night and all of the fun that will come with the challenging cross-country trip.
"A lot of people have their own themes and they'll dress up the whole way but there are dedicated dress up days like a Village People day and a Smurf day," he said.
"In past years they've done Lycra and Where's Wally and everyone dresses up so it's really cool - that's going to be half the stuff we take.
"We've got morph suits, ballerina tutus, matching shirts, it's all a bit of fun.
"When we get to Uluru, they've got that field of lights out there so they pick us up in buses and we go out and have drinks watching the sunset over the rocks and then we have this amazing five course meal."
Their colourful s...box will join a convoy of 250 cars and more than 20 support vehicles behind the starting line ready to rev their engines on May 8.
They will travel up to 700km per day on mostly gravel roads with overnight stops mapped out along the way where they will enjoy dinner, breakfast and packed lunches put on by local community groups.
She'll be right, it's a Ford!

Ms Turner said they were looking forward to taking their annual leave for an epic Aussie adventure across four states.
"We've never travelled this part of Australia before," she said.
"It's going to be a good holiday with a good bunch of people.
"We're looking forward to spending time together, hanging out instead of having to go to work.
"We're going to solve the world's problems from the inside of the s...box."
Box Rallies founder James Freeman said he started the event after both of his parents passed away from cancer within a year of each other.
“This is a chance to explore Australia, drawing teams from around the country to help achieve the extraordinary," Mr Freeman said.
"There will still be a number of surprises for the teams and it will be a truly epic journey.
"We’re grateful for the support of the teams who take part and the communities who help them to fundraise.”
The ForDad team has raise almost $7000 for the Cancer Council through Bunnings sausage sizzles, raffles and a unique idea to let community members place a painted handprint on their car in an honour of a loved one lost to cancer.
