A whole heap of huffing and puffing will be going on when firefighters clamber to the top of Auckland's iconic Sky Tower.
And a Kamo team hope tough training, including sessions with a personal trainer, will put them near the front of the pack as they raise funds for the Leukaemia and Blood Foundation.
Eleven of the brigade's volunteer firefighters have been donning full fighting kit - 25kg of it - and hitting the gym this week in preparation for the May 19 event which will require them to climb 51 flights, or 1103 steps.
Senior firefighter Hamish Cates believes the intensive gym work, under the scrutiny of Fitness Plus Health Club owner and trainer Jon Renes, could give them the team the edge.
"This is the Kamo brigade's seventh year of contesting the Sky Tower Challenge and so we wanted to mix things up a little with our training; with his background in training elite athletes Jon was the obvious choice to help put us through our paces," Mr Cates said.
