The 82-year-old broke 26 records at the national powerlifting championships in Christchurch.
That is not a bad effort by any account - even more so for someone returning from 18 months away.
Park, who weighs 67kg, recorded a 107kg squat, 62kg bench press and 161kg deadlift.
That made a total of 330kg.
Not only did that break the marks in his own age-group, it broke many in younger grades too.
However, he did not know he had been that successful until the Otago Daily Times called this week.
He had competed on the Friday and returned home to Greenfield in South Otago on Saturday morning before the competition finished.
"I didn't know I'd broken 26 records,'' he said.
"I knew there would be a few there because of my age. It tapers down into the younger ages.''
Park was thrilled to be back competing.
Not being able to breathe properly was the biggest issue and that limited the training he could do.
"I've had the experts doing heart work and lung work; they couldn't put the finger on it.
"I got to a totally different gentleman.
"It worked out and they finally found out I needed a bit more freedom in the muscles in my back to allow my chest to open better.''
He is not planning to stop competing.
The sport has enabled the former athletics coach to still get a competitive buzz after taking up powerlifting at age 70.
It followed a brush with death at 57 - he contracting septicemia while vaccinating lambs on his farm. That turned into meningitis and a blood clot developed in his brain.
It left him with a damaged brain, restricting his speech for a while and forcing him to stop coaching athletics after 20 years.
A stint in cycling followed, but he was forced out of that after smashing a shoulder.
He soon found powerlifting and that has stuck.
"It's a bit of competition.
"I've been a competitive person ever since I can remember being anybody.
"Powerlifting seems to have fitted into my living. It suits me. So I can carry on."
He has competed internationally and aged 76 set a then age-grade world record in Orlando, Florida.
His 196kg deadlift record stood for three minutes, before being broken by 500g.
He soon reclaimed it, by adding another 500g in Auckland. That remains his personal-best.
Other Otago athletes to have success at the national championships were Bible Lee and Juliana Picoli.
Lee won gold in the bench press-only category with a 55kg lift in the 58kg class.
Picoli won the 64kg class with a squat of 142kg, bench press of 58kg and deadlift of 130kg, totalling 330kg.
