Event co-ordinator Steve Thomas said the updated course looked fantastic and entrants were guaranteed a marvellous day out at the beach.

“The event is perfect for team bonding and families or groups just wanting to have some safe, active outdoor fun together,” he said.

“Also for HSC students and friends, what a great way to let your hair down and blow off some steam after the tension of the just completed exams.”

Fancy dress is the order of the day.

The fun starts at 10am with groups and businesses vying to win the Corporate Challenge Cup, while the main untimed Sand Mania event begins from 10.20am.

Entrants can take as long as they like and enjoy the course and its 27 obstacles.

Those who want more fun can buy a Multi-Mania ticket for unlimited action.

There is a separate Mini-Mania event for children aged up to 11.

To enter or register as a volunteer for the day, visit sandmaniapmq.com and be a part of the fundraiser for Tacking Point Lions Club, headspace and Marine Rescue Port Macquarie.

Sand Mania is a Tacking Point Lions Club event.

The club’s vice-president, Robert Bruce, said the 2017 Sand Mania would be the fourth time the event was staged.

“It caters for just about every age and it is a lot of fun,” he said.

Headspace program manager Lyn Stewart said headspace was excited to be involved with Sand Mania.

“The event enables headspace’s brand to be seen in the community helping to raise awareness and reduce the stigma of youth mental health,” she said.

Headspace plans to use its share of the proceeds for social inclusion activities.

Marine Rescue Port Macquarie unit commander Neil Yates said members made a large contribution of time and effort for the event.

About 70 members will volunteer on the day.

Mr Yates said Marine Rescue Port Macquarie would put its share of the proceeds towards the replacement of the boat launch rails used for the rigid hull inflatable boat.
