"They do so much for the community so it's only right to give something back," President of the Havelock North Rotary Club John Pollard said.
Havelock North volunteer firefighter Kevin Lay is one of the 15 that will be taking part in the 17km walk while also being kitted up.
"I haven't done any training but nah I think we will be fine," Lay said.
"I've done it before but not in the full firefighters suit but I think I will be okay, worse comes to worse we change it up and all of us do it as a relay but I don't think we will need to."
He said the money fundraised will be a great benefit to helping fund a new training centre at Havelock North.
"We are going to use the funds we get to build a training facility that we can use to help educate people about fire safety, so we can educate everyone from kids at kindergarten to adults about fire safety."
The Country2Coast Event is a non-competitive family fun event that utilises the Hawke's Bay Trails between three start points and Farndon Park in Clive. Participants can enter for a 3, 8 or 17km walk or run.
There are three start points and the start times are set out in the Event Information page.
Events will be timed, but they are not races, and there will be spot prizes only.
Firefighter takes on the challenge from fallen mate Brett "Gonzo" How
Sky Tower Challenge first timer Hastings firefighter Glen Varcoe says he's taking up the challenge that was laid out by Brett How before he died.
"Before he past he always wanted to do the challenge and get us at the Hastings station to try and join him but he never got the chance so where now taking up his challenge and giving it a go," Varcoe said.
He said he managed to get his opportunity after fellow Hastings firefighter Ken Laurie was offered 10 spots to fill for this year's challenge after having raised the most money as an individual in a team.
"She sort of put the call out of who wants to do it and there was a few of us who always thought about doing it and really you can't get a better cause to fundraise for so we thought we would give it a crack."
Varcoe says he hasn't done a lot of training but isn't really to fazed if he has or not.
"I suppose we will find out next month if it was enough or not, I'm only looking to compete not break any records."
But the most important thing is raising money for Leukaemia & Blood Cancer New Zealand and he says he has been so surprised by how generous people have been.
"We've been doing a lot of fundraising and have a few events planned still but it's amazing to see how generous people are with things like sausage sizzles they only cost $2 but people are paying $10 and $20 for them saying 'it's for a good cause' which is just great to see."
