Ocean Brown, who lives with autism and epilepsy, is challenging herself to run and walk 150 miles in April to raise £500 for charity.
The 19-year-old is marking World Autism Acceptance Month by setting herself a challenge and giving all the money raised to Autism Jersey and Healing Waves, causes which are 'incredibly close' to her heart.
She says one of the main reasons for setting herself the task is to tackle the stigma surrounding neurodivergence.
"It's often just seen as people lacking capacity and not being able to achieve what other people can, which is a big misconception as everyone with autism is their unique selves and we have our differences, but the word 'autism' shouldn't be used as a label."
Ocean originally wanted to swim around the island, but this was deemed too risky for her to complete due to her epilepsy.
When she was diagnosed, she found it hard giving up her passion of 14 years.
The 19-year-old says Healing Waves supported her through this time.
"As change is one of my biggest struggles with autism, it was really difficult to accept.
"Healing Waves stepped in and allowed me to surf in the sea with them and at the swimarathon most recently.
"The team are absolutely incredible, and they accept you for who you are."
Autism Jersey aims to help people in the island with the disability through a range of initiatives.
The charity holds coffee mornings, sibling support groups and family events to help those with the disability and their families navigate life and create an inclusive environment.
Ocean says her goal has always been to help people.
"I just want to be able to break that stigma.
"If I can change one person's mind on their thoughts of autism, it will make me happy.
"I just want to be able to make that difference for someone who might be experiencing discrimination or not getting the support that they deserve."
Islanders can donate to Ocean's JustGiving page to help her reach her target.
