A large inflatable unicorn will make a unique starting point for Darren Smith when he takes on the Let's Talk Lady Bay Laps this Sunday.
The regular swimmer will be joined by three novices in the Wilson Athletics Seven Legs team for the event.
"We are using sport to help create different friendship groups," Mr Smith said.
"Other then Kiara, they are not swimmers at all but it is about using a participation event as an opportunity to socialise.
Mr Smith, who had a leg amputated after a truck accident in 2016, said he has used sport a way aid his mental health.
"I haven't had a mental health diagnosis, but I use sport to help provide structure and camaraderie," he said.
"I have my gym friends and my swim friends and this event is bringing them both together, it is a way of using sport as a mental health tool.
"You can choose to stay at home and put limitations and barriers on yourself, or you can get out and stretch that out a little bit."
Let's Talk organiser Jacinta Roache said 14 teams had already entered the event, and more were expected prior to the start.
"Around 75 people have committed to the event which is fantastic," Mrs Roache said.
"This is a mostly non-competitive event but some people have a bit of white line fever.
"The primary function of Let's Talk is to achieve three goals - to abolish stigma, encourage help seeking and increase the confidence of the community to ask questions when they are concerned about people's mental health.
"We want people to engage in community activities and to remain active as this is one of the key factors in mental health.
"The foundation will do a sports event every year and link the idea that lifestyle choices and getting out is going to help with your own health and wellbeing."
