Keanna Macinnes narrowly missed out on a place in the Olympic final on a night where a new swimming superstar brought the house down at Paris 2024.

Léon Marchand won two individual gold medals in the same session, the first swimmer ever to do so at the Olympics, as he won 200m butterfly and 200m breaststroke finals.

The session also saw the first swimming world record of the Games, despite criticism all week that the relatively shallow nature of the pool was leading to unusually slow times.

China’s Pan Zhanle had no such trouble, flying to a stunning 46.40 as he left the rest of the field in his wake to take 100m freestyle gold.

Macinnes, meanwhile, was in action in the women’s 200m butterfly semi-finals, immediately after Marchand’s first appearance, with the crowd still electric.

Relying on her finishing speed, Macinnes let the fastest women in the field get away from her early, backing herself to come back on the final 50.

She showed remarkable strength to finish in fourth spot, in a time of 2:08.04. That was nearly half a second quicker than she had gone in the morning, but she missed out on a place in the final by just one spot.

Compatriot Laura Stephens edged her into ninth, and Macinnes was understandably disappointed at coming so close.

She said: “I’m a little bit disappointed, I won’t lie. It was tough to make it back, a season’s best would have done it.

“But I’ve swam really well here and I can’t allow that to put a dampener on it.

“That last 50 hurt but I knew that was my strength so even though I was quite far behind the Aussie girl (Abbey Lee Connor) in the other lane I thought there was maybe potential to catch her just be asked on how good my last 50 can be sometimes but I guess it just wasn’t to be today.”

Elsewhere, Katie Ledecky broke her own Olympic record to win the 1500m freestyle, her eighth Olympic gold medal and first of Paris 2024.
