The event is run with The Daily Post and funds raised go towards Literacy in Homes.
There are three tracks for the participants, including one for those without any experience while another will see the more experienced riders taking on the Redwoods. Major Mania is a 2km course, Massive Mania 4km and Mammoth Mania is 10km long.
There will be a giant bouncy castle for the kids to enjoy, as well lots of food stalls on the day.
Registrations are $20 and can be made online at www.bikemania.co.nz or on Sunday morning at 10am at the park. Official T-shirts cost $25.
The major prize is a bike from Cycle Zone.
Bikes must be checked before riders take to the tracks. This can be done free of charge on the morning or beforehand at Cycle Zone. There will be plenty of spot prizes and lots of fun on offer for those who head down. The day kicks off at 10.30am, with prize-giving about 2pm.
