Fareham charity Kids is looking for five people to join its team for the London Marathon on April 24 next year.
The Kids family centre, in Salterns Lane, supports around a thousand disabled children and young people in Hampshire.
The charity caters for all disabilities, offering after-school clubs, short breaks, overnight respite care and day trips.
It says that in its 45-year history, it has never turned a child away from its doors.
A four-bed unit is allocated for children to stay overnight or for a week if needed, which gives them the opportunity to have a sleepover with their friends.
Although the charity works alongside Hampshire County Council, it is reliant on public fundraising to keep services running across the south-east.
Kids has five golden bond places available with a minimum sponsorship requirement of £1,400 which includes a £100 non-refundable registration fee.
The charity has to pay £360 for each golden bond place so it is essential that the sponsorship target is met.
The marathon is one of the biggest fundraising events of the year for the charity and as previous runners have exceeded their fundraising targets, the hope is to raise about £15,000 for the cause.
Kitty McMonagle, fundraiser for Kids, said: ‘We are looking for someone who is dedicated to supporting disabled children and young people. It is a once-in-a-lifetime experience.
‘We don’t care if it takes 10 hours to do. If you are going to commit yourself to raising the funds, then we are willing to take anyone.’
If you are up for the challenge of joining the Kids 2016 marathon team, contact Kitty on 01329 312 312 or email firstname.lastname@example.org.
An application form will then be sent out and applicants will be chosen based on their level of commitment and the information provided on how the sponsorship money will be raised.
If the charity believes that the sponsorship target can be met, then the applicant will be selected.
