There is a 110km ride ending in Kumeu and a 15km ride from Shelly Beach Rd to Smales Farm in Takapuna. Two kilometre and 8km rides along the Northern Busway start and finish at Takapuna's Smales Farm bus station, where a mini-carnival will run from 7am to noon. Registrations are open until December 10 and individuals and teams may use their ride to fundraise for the Multiple Sclerosis Society.
Organiser Callum McNair says more than 3500 people are already registered and up to 9000 cyclists are expected to cross the bridge.
From 4am on Sunday, 160 Metrolink and Northstar buses will form a 2.3km-long barrier to protect riders from motorway traffic.
"We certainly hope this will become a regular event. NZTA are open to it but we really have to get it right this time," says Mr McNair.
GetAcross hopes cycling across the bridge will become the norm. Its campaign, assisted by the Auckland Harbour Bridge Pathway Trust, calls for a cycling and walking path under the bridge's southbound clip-on.
Trust director Bevan Woodward says its engineering feasibility report was signed off in August and a funder for a tolled cycleway has been secured.
"Now we are looking for an underwriter [to construct the cycleway]. We're approaching corporates and the Auckland Council. The underwriter will need to assume the risk but we believe the return is there."
Mr Woodward is disappointed the NZ Transport Agency will not support the project.
"It just isn't a priority for them. Even when we tell them that by charging a toll of $2 on users the Pathway will pay for itself, they are still not interested."
Building the cycleway is estimated to cost $31.3 million.
GetAcross will have a stand at Smales Farm during the Challenge, displaying a model of the pathway.
"We welcome people's feedback and we'll be gathering more support to get it built."
