LBC said everyday six children and adults in New Zealand are diagnosed with a blood cancer like leukaemia, lymphoma, myeloma or a related blood condition.
All funds raised will be used to support LBC services for patient and family members support. This includes running support groups, programmes and hospital visits. LBC also provides funding for research into finding cures and better treatments, raising awareness of the diseases and advocating on behalf of patients.
Mrs Richmond said their team started training in November last year completing a range of exercises to get fit and build up leg muscle.
"Murray is in the air force so we were lucky to get some steel BA sets, which is heavier than our firefighter kit...we do walks with that gear on, go to the gym and basically climb stairs wherever we can.
"After the first training, which was running up and down the rugby grand stand, I couldn't walk for two days...now it's easier but you need to keep on top of it to build that momentum," Mrs Richmond said.
Over the last two years the event has raised over $1 million due to the efforts of brigades across the country.
The fundraising target for the 2017 event is $900,000. With 900 firefighters taking part in the challenge this is a target of $1,000 per firefighter.
The challenge will be timed individually as well as in a team.
Ms Robertson said last year the fastest female completed the challenge in 13.57 minutes and the quickest male cracked 8.46 minutes.
"We are all aiming to get in done in 20 minutes but really I'm just hoping to get to the top in one piece."
