The festival format has been rejigged to include a four-kilometre event - called the Kids' Scamper - especially for eight- to 13-year-olds.

The festival is held on the foreshore of Lake Macquarie, taking advantage of the flat going between Warners Bay and Speers Point.

A half-marathon of 21.1 kilometres, and a 10.5-kilometre fun run/community walk ensure that mums and dads can take part, too.

The event will be staged this Sunday, August 29, and registrations are available online until tomorrow (Friday).
