"That is definitely the toughest part and we don't look forward to it," said Smith.
"We were in the front group last year when our engine blew up going past Maketu so, this year, we are trying to finish in the top three."
Judging how much fuel to put in versus keeping the boat as light as possible was another challenge for the crews.
Wheeler says they ran out of fuel last year when they were in the leading three boats.
"The key thing is to have a plan so you know who is going to do what before you start and where the pit crew are going to stop in and refuel. Communication is the key."
Sefton says the race concept was designed by Justin Martin, from Papamoa, and replicates what he calls "a manic day of endurance, constantly pulling people in and engines breaking down".
Teams entered are from Bay of Plenty surf clubs plus defending champions Red Beach, Muriwai, Sunset Beach (three crews) and Mairangi Bay.
Conditions are expected to be ideal for the race with a light swell expected.
