Community Links Wollondilly special needs case worker Carmel Flavell will take part in the annual YMCA Swimathon again this Sunday at Mount Annan Leisure Centre.
The event aims to raise funds to provide children with disabilities, the chance to get involved with swimming lessons.
Children with disabilities often require specialised instructors and facilities for lessons.
The money will also provide pool access, facilities and equipment.
Ms Flavell is a regular attendee of the event, swimming 1km last year.
She also has a personal fund raising page which has reached more than $650 — more than $450 than her goal of $200.
