The long jumpers hoping to win the Olympic title that Greg Rutherford took four years ago are going for gold.

But at least they only have one event to compete in.

Back at the Los Angeles Olympics in 1984, American Carl Lewis managed to win the long jump gold, as well as further golds in the 100m, 200m and 4x100m relay. Great effort.

Here comes American Jeff Henderson, ah that's a lovely effort, real height and trajectory to it and he goes ahead with 8.20m!

He puts Greg Rutherford down into second place.

The 1990s really were the peak era for some things. And the men's long jump is another.

Look how many leaps over 8.5m in the 90s!

Greg Rutherford - with all due respect - would not have been near the peak of his sport during the era of Carl Lewis and co.

And will Mike Powell's world record ever be beaten?

Tori Bowie wins her first semi in 10.90secs, easily through. 

Great Britain's Matthew Hudson-Smith has a huge smile on his face after smashing his personal best and booking his place in the men's 400m final.

He told BBC One: "That was crazy. I messed up on the transition on the top bend. I have no idea what just happened. It was improvised.

"My coaches and team-mates always tell me to control your emotions. When they went past me I thought 'OK', and just started kicking.

"When I saw the time, that I had come second and made the final I couldn't believe it. I still have a lot to learn and work on. It wasn't the best of runs but I'm really excited for the final."

It's all going on. Here comes Greg Rutherford for his first jump in the men's long jump final. 

He attacks it at pace, over eight metres - white flag!

Get that one measured. It's 8.18m

Incredible run from Brit Matt Hudson-Smith. Take a look at how he managed to scrape second place to push him through to the final.

Matthew Hudson-Smith judged it well as he made a mistake from the start to 200, but he corrected it - it was a great adjustment.

He conserved a bit from 200 to 300 to go for it at the end and you can't run 400m pushing all the way.

He put himself in a position to come off the bend and finish strong with a personal best. He is starting to establish himself with his consistency. He is in the final where anything can happen. Great to see him show some experience. Nice job.

Only one woman has worn Olympic gold in the 100m since 2008 - Jamaican Shelly-Ann Fraser-Pryce.

Gail Devers knows exactly what winning back-to-back golds is like after taking 100m glory in Barcelona and Atlanta. And she thinks Fraser-Pryce can make it a hat-trick tonight.

"You may see an Olympic record here," Devers told BBC World Service.

"For the last eight years, nobody has been faster than her when it counts. Her and Usain Bolt have the same stats.

"I don’t care if they say she is injured. If she makes it to the final, you better watch out. She has experience and that girl runs with heart. And that is what a true champion does."

Up next on the track, the women's 100m. The best name in athletics goes in semi number three - English Gardner...

Re Matt Hudson-Smith's brilliant PB to make Olympic 400m final from lane eight. Before each race he reads a page of Michael Johnson's book 'Slaying the Dragon'. The page in question is about Johnson winning the US Trials 200m... from lane eight.

Great Britain captain Kate Richardson-Walsh was delighted with her side's form after they beat United States 2-1 to finish their group with five wins from five.

“If you’d offered us top spot at the start of the week I’d have bitten your hand off," she said. "All the sides are excellent in this tournament so I’m really proud of what we've done so far.

“We had to show resilience tonight. USA are full of positive energy and resilience so we had to feed off that. Momentum plays a big part.

"The Dutch, Argentina and Australia always do it well. They keep building the performances at tournaments and that’s what we’re doing here.”

Matt Hudson-Smith can hardly speak in his post-race interview. Absolutely delighted with that race. And rightly so.

That time puts him in the top eight this season. 

Javelin is not KJT's strongest suit, but she will still be disappointed with her performance here.

This was her best throw of 36.36m, nearly 6m under her personal best.

She will hope for much better in the decisive 800m at 03.18.

World 400m champion Wayde van Niekerk is into the final after finishing second in the second of three semi-finals.

He tells BBC One: "Yet again it is another injury free race and the body is slowly catching up. I feel good."

On facing reigning Olympic champion Kirani James and 2008 gold medallist LaShawn Merritt in Monday's final, Van Niekerk adds: "They are quality guys and I will have to dig deep and put out the best performance that I can.

"It is a new competition, a final, new challenges, so I have to take it as a new day and put my best foot forward tomorrow."

  Here's how Trinidad and Tobago's Machel Cedenio won the second men's 400m semi  

Matt Hudson-Smith had to treat his semi like a final and he is second in 44.48!

Great effort and a personal best. He is in the final. The British record is 44.36!

It's a brilliant run from Matt Hudson-Smith! He finished like a train and might have nicked second...
