Walker, who competes in the 90-94 age group, hit the wall first after a powerful 50m Butterfly, with a time of 1:50:32, before backing up with gold in the 200m Individual Medley, 100m Breaststroke, and 200m Breaststroke.
He won silver in the 200m Backstroke.
Asked for his secret to ageing well, Walker tells me the swimming helps, but mostly it’s “just good DNA”.
“I don’t worry about how old I am anymore,” Walker says, “age is just a number and I just try to stay as active as possible.”
The next FINA World Masters Swimming Championships will be held in Fukuoka, Japan, in 2021.
“With any luck, I’ll still be diving off the blocks and going for gold,” Walker says.
We don’t doubt it for a second!
