Teens and their carers will run a military assault course for charity.
Residents and staff at Teasel Close children’s care home in Broadfield entered The Nuts Challenge Mud Run to raise money for Children in Need.
Carers said the challenge would boost the children’s confidence and help them in their futures following a successful first run last year.
Up to five 15 to 16-year-olds and around a dozen staff will take part in the 7km obstacle course on March 1.
Kieran Sparks, 16, has been going to the gym three times per week and has given up smoking to get fit for the mud run.
He said: “I’m determined to do two laps to raise more money for charity.
“I just want to raise as much money as possible.
“I feel good about doing it.”
Chris Willard, 35, of Horsham, a carer at the home, took on organising the event again this year.
He said: “We’ve got some quite determined kids .
“They want to help other kids that are in a worse position than they are in.
“There’s been quite a positive vibe.”
He added: “It will be a massive sense of achievement and give the kids more confidence.
“In life, there are lots of challenges that look like you’ll never be able to do.
“It gives the kids something to look forward to and is team-building for us too.”
One of the teens who took part last year completed the course despite it taking her three hours to do so.
A 60-year-old staff member also took part.
Chris said: “It shows the commitment level the staff have to the kids and to completing the challenge.
“There’s a lot more staff this time round now everyone is more aware of what the challenge is.
“Everyone’s more determined this time.”
Samira Manassib, a carer who ran the course last year, said: “You see another side to them.
“It brought qualities in them that you didn’t get to see every day.
“I got hurt and one of the kids that did it who struggled to show empathy day to day showed compassion in the moment.
“In that day they all supported each other in getting to the end and completing it.”
She added: “It gave them so much confidence.
“It was so nice to see afterwards.
“They are smart kids and they are a lot tougher than people give them credit for.”
