Beating the women's record in the Firefighter Sky Tower Stair Challenge was training motivation for Whangārei firefighter Ady Mckenzie.
But the experienced athlete, with a number of marathons under her the soles of her running shoes, said her cousin being diagnosed with leukaemia last Christmas gave her the mental motivation to scale the 51 flights of stairs in the Southern Hemisphere's tallest building.
On Saturday firefighters from around New Zealand, including several Northland brigades, competed in the challenge, which is an annual fundraiser for Leukaemia and Blood Cancer New Zealand.
Mckenzie raced last year and won the women's "donned and started" category in a time of 13m 11s. Donned and started means the firefighters are fully kitted out with their breathing apparatus that they use while racing. If they run out of air while pounding up the 1103 stairs they are eliminated. The women's record stood at 12m 48s.
"The plan was to go hard from the start," Mckenzie said of this year's race.
