It will be the "Clash of the Tandems" during the Redwoods Coast at the Rotorua Bike Festival in February.
The Redwoods Coast was a hit at the first two festivals with large crowds of spectators and it's returning this year in all of its lycra glory.
Riders start at the top of a steep, tar-sealed hill at the northern entrance to Rotorua's world-renowned Whakarewarewa Mountain Bike Park.
No pedalling is allowed and whoever coasts furthest down Nursery Rd and on to Long Mile Rd is the winner.
Rotorua deputy mayor Dave Donaldson piloted the "X-Men" tandem to victory in the two-person category in 2013, with passenger Martin Croft on the back.
