Thrill-seekers can tackle the world's biggest inflatable obstacle course to support hundreds of unpaid carers.

There are still 20 charity places left, out of 50, on the Gung-Ho! Norwich 5K challenge at Earlham Park on Saturday, September 16.

Money raised through these places will go towards Norfolk Carers Support.

Established in 1996, the charity provides one-to-one support, youth groups and emotional and practical support to children, teenagers and adults who care for loved ones.

Up to 5,000 people are expected to take part in the Gung-Ho! Norwich race.

Participants will reach speeds of 40mph and the course features 10 obstacles, including the five-storey-high, 200ft-long Thriller slide.

There is no age limit but the minimum height requirement is 123cm or four feet.

Catherine Bibb, young people's services manager for Norfolk Carers Support, said: 'The Gung-Ho! Norwich challenge is a fantastic opportunity. It is a great way to raise additional funds and it is a good way to get the word out about what we do. The funds we raise support the work we do with people of all ages across Norfolk.'

Over the past year, Norfolk Carers Support has helped more than 100 young carers aged five-16; 150 young adult carers aged 16-24; and more than 2,000 adult carers aged 16 and over.

Its young people's services cost about £180,000 a year to run.

Miss Bibb added there is a rise in demand for its four young carers' support groups in Norwich, which are each attended by 20 people.

There is now a waiting list for the groups.

Demand for the one-to-one support work for 16-24-year-olds across the county is also increasing.

Miss Bibb said there was an estimated 10,000 young carers in Norfolk.

She added: 'Norfolk Carers Support makes life more manageable for people who give up their time for someone else.'

Talking about how the organisation supports young people, Miss Bibb said: 'We give young people a break and a childhood. The groups make them realise they are not alone.'
