The biggest difference between McIntosh today and Ledecky back in April was on the first and last 100s. McIntosh was already half a second under Ledecky’s old record and also half a second under her own World Record at the 100 mark. She remained under Ledecky’s record the remainder of the race but fell off pace of her World Record half way through the race.
With her swim today, McIntosh now holds four of the six fastest performances all-time.

Any racevideos?
Bow to greatness!!!
Summer McIntosh is still on track to become future GOAT
Nice! Glad she’s recovered from her illness. Hoping to see her break that 200 Fly world record
WR Watch for the 200 Fly…? She was mad when she didn’t get it in Singapore. Anger’s a good motivator.
Monster swim. Just pipped Arnie’s former WR too.
She looked worn out and furious after losing to Katie in FL. She very literally took that personally!!!!!
But did you see the 400 free in Singapore? It wasn’t even close.
She was sick at that time
