The final discipline in semi-final A of the women's modern pentathlon - the laser run - has just begun.

The laser run consists of a 3,000m run, split into five 600m laps, and four visits to the shooting range.

The athlete with the most points going into the laser run - in this case Italy's Elena Micheli - starts first, with the remaining athletes starting with time handicaps – one second for every point they’re behind the leader.

Defending champion Kate French is going off second and fellow Brit Kerenza Bryson is sixth.

They need a top-nine finish in the 16-strong semi-final to reach the final (Sunday at 10:00 BST).

Team GB’s silver medallist in heptathlon Katarina Johnson-Thompson, speaking to BBC Radio 5 Live: “I am sleepless! The morning is jam-packed and it is really hard cause you are dosed up on caffeine.

“My analytic brain is going over ‘what if’ and with heptathlon that is always the case.

“Ultimately, it is like a pendulum swinging. On one side we have the raw emotion of finally getting the medal and on the other side we were clinging onto the gold - we were so close.

“I feel so lucky that I've had this second chance after my ruptured achilles injury. That is a big injury for an athlete to have, I am grateful I have managed to turn it around and get back on the podium."

On her celebratory meal tonight: “Pizza and pasta. I want a bottle of wine on the table and everyone sharing food feeling absolutely sick cause you’ve eaten too much – that is what I want the vibe to be like.”

Look at that strength from Erin McNeice!

With two dives to go, it's looking a bit precarious for Great Britain's chances of making this 12-man final.

Kyle Kothari has climbed to ninth but Noah Williams is down in 13th. A lot can still happen though.

There's a reason why Slovenia's Janja Garnbret is regarded as the best in this sport.

She's just finished the third wall and has 74.8 out of a possible 75 points.

GB's Erin McNeice is down in fourth now.

It's 9.6 points for Erin McNeice on the final wall. She was so close to the 25 point hold!

The Brit has ended the boulder part of the final with 59.5 points and is currently in third.

USA's Brooke Raboutou is in first with 74.4.

Erin 'McBeast' McNeice is tackling the final wall in the boulder part of the final and she's already secured the five point hold.

She'll want and need more than that.

Japan's Ai Mori becomes the first to conquer the third wall.

That's how you do it!

What a fightback from Kyle Kothari, who delivers a great third dive that scores 81.60!

But Williams has lost quite a bit of ground with 52.70 for his reverse three and a half somersaults.

At the halfway point Williams is 11th (total 206.90) and Kothari 17th (189.00) after that costly second dive.

China's Cao Yuan (236.90) leads at the halfway point, closely followed by Yang Hao (232.05). They look like they are going to be hard to beat as their country look to take a clean sweep of all the diving golds here.

Australian Oceania Mackenzie only secured 4.9 points on that difficult third wall.

She moves to the top of the leaderboard on 54.7 points with Erin McNeice tied second on 49.9.

A blow to Erin McNeice's medal hopes as she fails to take any points from that tricky wall three. She remains in a strong position on the leaderboard, though.

It'll be interesting to see how the other women cope with that wall.

Erin McNeice is having a good look at this third wall. It's proving rather difficult at the moment and she's failed to secure any points so far.

GB's Erin McNeice is back in action on wall three as she looks to continue this tremendous start to the final.

Erin McNeice has burst onto the scene.

She is walking away from the Olympics qualifiers with two medals, she is going from strength-to-strength and she is walking into this event with nothing to lose – making the final is a massive achievement in itself.

Great Britain's Noah Williams has catapulted himself to third in the standings at the end of the second round with 77.40 for his double somersault with one and a half twists from handstand.

But Kyle Kothari will not be pleased with that second dive of his, he seemed to get very close to the platform and did not hold his form well, scoring just 30.60 to sit 16th. The 26-year-old will need to improve if he is to make the top 12 to go through to the final.

So, we heard yesterday that Toby Roberts is called 'The Terminator', but that may have been topped this morning by Erin 'McBeast' McNeice.

I love sport climbing.
