The teenage brothers, like their father, have also played rugby. But they are now fully focused on their athletics ambitions.
“[My aim] would be trying to get into Diamond Leagues or another huge goal would be the Olympics,” Donovan said.
“That’s always a goal I’ve always had… to be able to perform at the same level that our grandad did.”
Lawson has his eye on further international selections and setting British records for his age group.
“Long-term wise, I think in 2028, obviously it’s a long shot, but it would be good to see whether I could get a place [at the Olympic Games],” he said.
“In 2032, it would be good if I could get qualified, maybe come top eight, and then maybe see if I could get top three.”
Geoff Capes won two Commonwealth titles and came closest to an Olympic medal when he placed fifth at Moscow 1980.
He was World’s Strongest Man in 1983 and 1985. Such competitions are another avenue that his grandsons could take if they wanted to follow in his footsteps.
“It looks a lot of fun. But then it’s also completely another lifestyle,” Donovan added.
“You’ve just got to put everything into that and you’ve got to go crazy for it.
“That could be in the back of my mind, but then also the Highland Games could be an option.”
