It's the Kiwi version of the Coolangatta Gold but with special Mount Maunganui flavouring.
Starting with a 5km beach run in the shadow of Mauao, athletes then take on a spectacular swim leg which includes a jump off Moturiki Island's blowhole, before bringing things home with a 12km ski leg and a 6km board paddle.
Entries are now open for you to race it as a team or as an individual - it's a bucket-list event.
Keep an eye on our Mount Monster Facebook page for ongoing information.
