KIM Mackney knows a thing or two about winning world masters rowing events.
On Saturday, the Sydney-based rower and 1972 Olympian clocked up yet another victory, this time in the mens G2 category.
It was his first for the event but just among dozens of gold medals he has won in the world masters alone.
When asked what his career tally stood at, Mackney stood puzzled.
"I don't know how many I've won actually, it would be maybe 30 or 40," the Glebe Rowing Club member said.
"There was one event when I won six and another where I won four but I don't actually know the total."
One of the most tried veterans, Mackney has not missed a rowing season for 54 consecutive seasons.
And at the age of 66 he is now grateful just to be competing; any wins are a bonus.
"I've never stopped, I've been rowing since 1961 and this is my 54th season without a miss, you might say I'm an addict," Mackney said.
"I won today, but I don't have to, it's a therapy for me and it's good for my brain. It's like you're in another world when you're rowing.
"A lot of people our age can't even get in or a boat or are dead, so just to be able to get out on the water is great and you have to take advantage of it."
Mackney will also compete in a social event on Sunday.
