She said it was a good course which went up the side of Mount Ngongotaha.
"I like undulating courses and it is a challenge, you have to push yourself."
McCready recorded a winning time of 27m 29s.
The race was held during the Rotorua A&P Show and started and finished at the A&P showgrounds in Ngongotaha.
Meanwhile, the men's race was taken out by another regular at the event, Tirau's Mark McGlashin.
The dry stock farmer said he does a lot of running up hills on the farm which helps prepare him for the annual race.
"It is just a good, steep and rugged run," McGlashin said about the race.
"It is getting harder and harder but it is a good run, the guys who organise it put on a good event."
The win was McGlashin's fourth King of the Mountain title and he finished in a time of 20m 45s.
He still needs to win five more titles to eclipse local legend Winston Fleming's record of eight King of the Mountain crowns.
The top Rotorua runner home in the men's race on Saturday was teenager Ash Gower-Rudman, 17, who finished second, one minute behind McGlashin.
Gower-Rudman plays football for Rotorua United and said he was doing the race as part of his pre-season build-up.
Organisers said they were not certain how long the course was on Saturday but it would have been between 4km and 5km.
Well-known runners to win the event in the past include Colin Smyth in 1971 and Jack Foster in 1972/1973.
The race has been held since 1970.
