BBC Sport at London StadiumThe women's 400m hurdles promises to be one of the athletics events at Paris 2024.
All being well, Femke Bol and American star Sydney McLaughlin-Levrone will finally go head-to-head in an epic showdown for gold.
Together they have run 17 of the 20 fastest times in history.
McLaughlin-Levrone improved her world record to 50.65secs in June, before Bol set a new European record of 50.95secs in July to become only the second woman to ever go under 51secs in the event.
That was certainly another statement performance by Bol.

Women's pole vault
Brit Molly Caudery has high hopes for her Olympic debut in a couple of weeks and she's made a positive start to today's meet.
Caudery comfortably cleared 4.50m - well below her season best of 4.92m.
It's early stages of that event with all but Olivia McTaggart of New Zealand, who failed to clear 4.35 with her three attempts, still in the mix.

Two-time world 110m hurdles champion on BBC TVIt was a really strong race from John. She controlled the race right from the start and if you can manage your pace right the way through then it makes a huge distance.
I think it's blustery down there and the wind is changing. It's a bit of luck with the draw.

Came back from injury this year, I pulled my hamstring in January. The trials for the Olympics came too early for me. I had a good race in Dublin a couple of weeks back but I knew I had plenty left in the tank. I can't believe it.
"My 100m is really good. I knew the guys outside me are really good 200m so if I was beside them then I knew my kick home would be good enough."
