When he began to commentate on his son's school sports days, he might not have thought where the journey would lead them both.
"Running is coming home" was the cry of the Oregon crowd as Jake Wightman crossed the line to win the 1500m world title.
The 28-year-old looked as shocked as anyone when he held off the Olympic champion.
The first British man to win the world 1500m title in more than 25 years was Wightman.
It could have been even more special if his father had called the race.
He told the radio station that he tries to drown out his voice as much as he can.
There is no one else who is calling the race. It's nice to have this, I've had many stinkers where he's called it.
Jake said "he puts in as much effort if not more than me so I hope he can celebrate it as much as possible".
Jake was raised in Scotland where his father was the chief executive of Scottish athletics.
Susan competed in the marathon at the Commonwealth Games and European Championships, as well as representing Team Great Britain in the same event at the 1988 Olympics, with both of her sons.
He failed to qualify for the 2016 Olympics and finished 10th in the 1500m at Tokyo 2020.
Mo Farah is the only British runner to have run quicker than his personal best.
When his son crossed the line, the father allowed himself a moment of joy. He is the world champion.
He reminded Jake that the next focus was the Commonwealth Games, which start on July 28, in a busy summer that includes the European Championships.
A contributing factor to Jake's success is that his coach and commentator are aware that there is still a lot of work to be done.
The threat is always that if I am not impartial or start coaching over the microphone I will get taken off the 1500m.
His achievement is his. I'm in the middle of something.
"You're thinking 'I know that guy' when you watch it, so it was really weird," he said.
Jake thought "something's gone wrong" when he crossed the line, and he was still shocked that he had beaten the man.
He describes it as a "scarring experience" in Tokyo but there isn't much time to celebrate.
He said he had to make sure he didn't miss his travel out of here because he was flying home tomorrow.
The only annoyance is that there is still a season to go. I would be a bit large if I didn't have other champ to prepare for.
