Jamaica’s Shelly-Ann Fraser-Pryce is up next. How will she respond?

The Ivory Coast's Marie-Josee Ta Lou makes a statement of her own as she runs a 10.78, slightly faster than Elaine Thompson-Herah.

A superb run from GB's Daryll Neita, who runs a personal best time of 10.96 to qualify in second place. Nicely done.

Roberto Colombi: How brutal is BMX! Two serious crashes but thrilling viewing. Not for the faint hearted.

Oh that is rather impressive from Jamaican Elaine Thompson-Herah.

She made that look like a stroll in the park, despite recording a 10.82.

Effortless, and seriously good.

There's been another serious crash in the BMX, this time in the women's semi-final first group with Australia's Saya Sakakibara needing medical attention on the track.

"Exactly how Kye Whyte needed that race to go. He's in a great place.

Picks his way through and like I say, if you blink you miss it with Kai.

His power is phenomenal but his track speed is another level."

GB's Kye Whyte has cemented his place in the final by winning the final heat. He again showed tremendous pedal speed to keep his rivals at bay and crossed the line in first place.

Three-time Olympic sprint gold medallist Veronica Campbell-Brown believes the women's 100m will be a "fierce battle from the first round all the way to the final".

"No doubt the women's 100m is the most anticipated race in Tokyo," said Campbell-Brown.

"It is so loaded with talent and it's going to come down to the ones [who are] able to handle the pressure - who can execute and can run the race of their life, because I really think that it will take 10.70 seconds, if not 10.60, to win that 100 meters.

"Shelly-Ann [Fraser-Pryce] has gone 10.63 seconds so far and so no doubt she may be the most hunted."

The final heat of the men's semi-finals is under way after a delay caused by a huge crash in the previous heat which saw defending Olympic champion Connor Fields going down heavily and needing medical attention on the track.

He has now been taken away on a stretcher for further treatment.

The crash also put paid to world champion Twan van Gendt's chances of making the final.
