The veteran horseman registered his 100th win at the Dunedin track as a trainer when Mr Majestic trotted to victory.
The milestone adds to Malcolmson's even better record as a driver at the venue. He gained the 100th of his 129 career wins in the sulky there when winning on Sarobi in December of 1996.
As proud as he was to have achieved his 100th training win, Malcolmson was quick to deflect the praise for his accomplishment on to others.
''I think a lot of people don't realise the work that goes on behind the scenes to win one. I couldn't do it on my own.''
''I have had a lot of good staff over the years. It has been amazing.''
The humble Malcolmson also complimented the owners who have filled his stable with horses for nearly five decades.
''I have had some great owners from go to whoa. It has been a big help to have good owners.''
One other person stands out for their contribution. Malcolmson's late wife, Doreen, played a big role in the running of his stable, until her death in 2013.
''She has been a big part of it and it is unfortunate she is not here to celebrate it,'' he said.
''She did most of the nominating for races and trials. She always made sure everything was spot on and ready to go.''
Malcolmson started his journey towards 100 training wins at Forbury Park when scoring with Treasure Girl in February, 1972.
''When I started out it was the old clay track at Forbury Park. There were no lights.
''It has certainly changed a lot since then. They put lights in and I remember Cardigan Bay racing around Forbury Park in the early stages.''
Prior to that, he had scored his first win as a trainer and driver with Pleasure Girl at Ascot Park, Invercargill, in 1968.
Our One landed Malcolmson on the national stage in 1978,
but the trotter also made him think of what might have been.
The squaregaiter won the midweek lead-up to the 1978 Rowe Cup, before galloping when she was about to challenge eventual winner Ritch Hill.
''She beat No Response on the Wednesday night and she was sitting behind Ritch Hill [in the cup] and she was just jogging.
''I should have stayed there - there was no passing lane.''
''I all but headed him [Ritch Hill], but his wheel was on her front legs.''
In trying to keep Our One clear of Ritch Hill going around the clockwise circuit of Alexandra Park, she galloped, he said.
''Reg Clapp was the commentator at the time and after the race he said 'You should have won that'.''
Malcolmson was able to get some consolation courtesy of Vita Man, three years later.
Although he only added one win to his trainer's tally at Forbury Park, he helped lay the platform for Malcolmson's career. Vita Man won the 1981 Flying Stakes at Addington, then ran second in the Great Northern Derby to Melton Monarch. That earned Malcolmson and the horse a trip to Perth, where he competed fairly enough, the trainer said.
After their return, they won the Ashburton Flying Stakes, beating that year's New Zealand Cup winner, Bonnie's Chance, by more than six lengths.
Following those successes Malcolmson built up a large team of horses that contributed evenly to his 100 Forbury wins.
None would better Our One's record of four wins there, although handy mid-2000s mare Just Another Lover equalled that tally.
Talented types such as Beau's Delight, Tricky Trent, Diamond Admiral and Whatafilly would all add three wins each as Malcolmson edged towards his milestone.
Fast-forward to 2017 and the hustle and bustle of training a large team is no longer.
''Just now I am winding down. I am lucky to have Bob Straight to give us a helping hand. He is great.''
It would be left to Mr Majestic - the only horse not owned by Malcolmson of the four he has in work - to complete his 100-win milestone.
The trotter did not let him down when, on a wet Forbury Park night last month, he and driver Robbie Close saluted the judge.
After the record books were checked and double checked by Harness Racing New Zealand and the Otago Daily Times and Malcolmson was notified of his record, he was a proud man.
''There is no doubt about that.
''It is something to be proud of, to be honest.''
