Kerr had become the first Scottish athlete to win a global indoor gold since Tom McKean and Yvonne Murray did so 31 years ago and his immediate reaction was to seek out a Saltire to swaddle himself in as the Glasgow crowd went daft.
Doing this mattered. But doing it here meant it mattered more. “Coming back home and doing myself proud is a great feeling, a full-circle moment,” he told BBC Scotland.
“I think I burnt more energy celebrating than I did in the race, which was a bit embarrassing. I wanted to make sure I wasn’t acting emotionally out there. I tried to keep a patient head and I really stepped on it with 400m to go.”
The manner in which Kerr claimed victory was reminiscent of the way in which he bodied reigning Olympic champion Jakob Ingebrigtsen to take World Championship gold in Budapest in August.
In the months since, the Norwegian has had one or two things to say about Kerr who, sportingly, has offered one or two pointed observations of his own.
There’s an enjoyable niggle there that will only build as this summer’s Olympic Games looms.
Ingebrigtsen has not been in Glasgow this week, but events will not have escaped his attention. They will have served as a further reminder that Kerr is capable of upgrading the bronze he won in Tokyo three years ago.
“It’s a massive stepping stone towards bringing back more gold medals to Scotland, to Great Britain, to Team GB,” Kerr said of this success.
“All you can to do is make yourself available when the chance of gold is there. That door opened today.
“After Budapest, I knew I had the ability to come home and do something really special. I wanted to turn up to these championships and show what’s possible for a Scottish boy that grew up here, is born and bred here.
“I’m trying to inspire the next generations of runners to show that if you’re from here, you can be a champion.”
