Colombia's Martha Bayona takes victory in a tight second semi-final, ahead of Mathilde Gross of New Zealand and Hetty Van Der Wouw.

Emma Hinze is among the riders who miss out.

The finals will take place later this evening, at around 8pm.

Lea Friedrich leaves nothing to chance in the first semi-final and she will be joined by New Zealand's Ellesse Andrews and Belgian Nicky Degrendele in the final later today.

Unfortunately Emma Finucane and Katy Marchant were unable to make it through the women's keirin quarter-finals earlier.

But we should still be in for a great conclusion to the event.

Lea Friedrich of Germany is aiming to defend her world title and she will be among the riders battling for a final place in the first semi-final.

Her compatriot Emma Hinze also won her quarter-final, and she is in the second race.

It's a third gold of the evening for Great Britain!

Kadeena Cox successfully defends her world title in style, beating Kate O'Brien's time by more than two seconds to the delight of the crowd inside the Sir Chris Hoy Velodrome.

Australian Erin Normoyle takes bronze.

A strong finish from Canada's Kate O'Brien puts her in to the gold medal position with a time of 38.136 seconds.

Over to Kadeena Cox!

Erin Normoyle of Australia guarantees herself a medal as she sets the bar at 38.297 seconds.

Last year's runner-up Kate O'Brien is up next, before GB's Kadeena Cox takes to the track.

Anna Taylor betters American Samantha Bosco's time, topping the standings with 38.565 seconds.

Xiaohui Li of China will aim to give herself a shot at a medal, but she can only place second with three talented riders still to come.

Is another gold on its way?

Great Britain's defending champion Kadeena Cox qualified fastest in the women's C4 500m time trial.

The 32-year-old is joined by last year's silver and Bronze medallists Kate O'Brien of Canada and New Zealand's Anna Taylor once again in this year's final.

Can she come out on top in Glasgow?

It's going to be Archie Atkinson and Benjamin Westenberg competing for the gold, with a huge battle for bronze behind...

And it's GOLD for Atkinson!

A massive final push to the line seals the world title in style. He can't quite believe it.

Ireland's Ronan Grimes takes the bronze.

We restart, with GB's Archie Atkinson and New Zealand's Benjamin Westenberg a lap up on the rest of the field.

The board is reset to nine laps. Away we go again...

Oh, ouch!

A rider comes down and another ends up going over the top of him.

Both are off the track so we're continuing for now with less than five laps remaining...

No, the gun goes and the race is neutralised with three laps to go - but it will be restarted with nine remaining to give the riders time to get back up to speed.

Nick Blincoe loses his lap advantage, leaving GB's Archie Atkinson and New Zealand's Benjamin Westenberg in charge with just over 10 laps remaining!

In the first event on the track tonight, Great Britain's Frances Brown set a world record as she won women's C1 individual pursuit gold.

Brown crossed the line in four minutes 10.941 seconds, claiming victory over Wangwei Qian of China by over six seconds.

Great move by GB's Archie Atkinson, who joins Nick Blincoe and Benjamin Westenberg in stealing a lap on the main group.

We've got around 30 laps still to come.

What's the scratch race?

We start with 60 laps on the board and it's a race to the finish line, but tactics are crucial.

Riders will try to break away from the peloton and gain a lap on the competition, as we're seeing here with New Zealand duo Nick Blincoe and Benjamin Westenberg. They waste no time in gaining an advantage here - but there's a long way to go...

We've got a field of 24 lining up for the start of the men's C4 scratch race.

Maike Hausberger outdoes Sabrina Custodia to guarantee herself a medal with two riders to come.

But what colour will it be?

China's Zhenling Song goes in to top spot with a time of 42.318 seconds.

Only defending champion Amanda Reid of Australia can deny her gold now.

Daphne Schrager is taken away and hopefully she can make a quick recovery from that fall.

Last year's runner-up Sabrina Custodia sets the fastest time, posting 42.856 seconds, to lead with three riders left to go.

We wait for Daphne Schrager to receive medical attention before the action can resume on the track.

Another rider who suffered a nasty fall today was Dutchman Mathieu Van der Poel, who recovered from his crash to win the men's road race in Glasgow.

Here's how he claimed victory in dramatic fashion.
