Here’s a bit more from Britain’s Lina Nielsen, who earlier finished seventh in the women’s 400m hurdles final won in dominant fashion by Femke Bol.

Nielsen’s twin sister, Laviai, revealed in an emotional interview after her 400m final yesterday that their coach, Tony Lester, only recently suffered a cardiac arrest.

“I’ve learned a lot from that first major final experience. I think those medals are in my reach so I’m very disappointed,” Nielsen said.

“I would have liked to have made Tony proud today, I know he’ll be gutted seeing a seventh place when I know I could have snuck into the medals.

“But I can’t dwell on it too much. We have the Olympics coming up so everything is working towards that.”
