"I'm 58 years old, and I did it in the time of a 28-year old. I'm pretty happy with that," Bush said.
The maximum time limit allowed for a 58-year-old man is three minutes and twenty four seconds.
Bush said the purpose of the test was for officers to push themselves to the limit and to try to replicate what might happen in the field.
"The public expect their police to be fit and healthy, and we've got to maintain that."
As to how he found it; "it hurts".
"You do go into a level of oxygen debt. The last part is really hard - you're running on rubbery legs."
Bush believed it was important to take the test himself, because he expects all of his staff to qualify.
"If it's good enough for them, it's good enough for me."
The Physical Competency Test is taken by all serving police officers, up to the rank of Commissioned Officer, every two years.
But Bush thinks maintaining physical fitness is important for everyone.
"It's good to stay fit. It doesn't matter what walk of life you're in."
