Rio-bound Kent athletes look to be hitting form at the perfect time after some shining displays at the Diamond League meeting in London.

In the final meeting before the Rio 2016 Olympic Games begins on Friday week, Hythe hurdler Jack Green ran his third-fastest ever 400mH time on Saturday afternoon to claim fifth in an elite field packed with Rio podium prospects.

It was the 24-year-old's first run at the stadium since he crashed out in the semi-finals of London 2012, though there was no repeat despite being handed the outside lane as he made his trademark flying finish to dip under 49-secs (48.99) for the second time this season.

Green had also clattered a hurdle and did not finish in the European Championships Final in Holland earlier this month and he admitted: "I'm really pleased, obviously the final in Amsterdam didn't go to plan, so we tried a new stride pattern today and that was my third fastest time ever.

"It was a perfect confidence booster, I haven't raced here since the Olympics so it's a privilege to be back."

Adam Gemili helped the GB 4x100m relay A team to run the fastest time in the world this year on Saturday afternoon.

Gemili, along with James Ellington, James Dasaolu and CJ Ujah stopped the clock in 37.78secs, just ahead of the GB B team who also cracked 38secs.

Gemili claimed GB were a genuine medal threat in Rio and said: "We are a great squad and really get on with each other.

"There has been a lot of hard work from a lot of people to make this team stronger. We are all running really well and are very confident.

"We believe we can go out there and challenge the world's best."

Gemili's Blackheath & Bromley AC teammate Asher-Smith finished superbly after a slow start to claim fourth in the women's 100m.

The 20-year-old British record holder's time of 11.09secs in the final - which she ran in the outside lane - was two-hundredths slower than the semi-final time which earned her third place and her spot in the final earlier in the session.

ivory Coast's Marie-Josee Ta Lou won both the semi and the final in a new PB of 10.96.

Asher-Smith said: "I'm really happy to run another 11.09, although I would have liked to have run a PB, I feel in that sort of shape. But when you are facing headwind, that is all you can do.

"The London Diamond League is amazing, it feels as though you are at a major Championship. You raise your performances at those champs, and that's what I feel everyone has done here. The crowd have really well supported athletes from around the world."

On Friday night Gemili ran a season's best 20.07secs to finish third behind fit-again Usain Bolt in the 200m.

Gemili - who had been suffering from a cold in the lead-up to the event - claimed: "It is a good indicator of where I am, at the moment. What better way than to run in front of a packed Olympic Stadium, it is a great feeling. It was fast, Usain is fast!

"It was key to run here but I would have liked to have gone under that 20 second barrier.

"I have more work to do and hopefully I can get myself into that final in Rio. It wasn't to be today but maybe it will come in the near future. I've been working on that speed endurance and holding it in the final few metres, when that comes right, the time will come."

He added: "The atmosphere was unbelievable. When they called my name out they were so loud. I was getting tingles but you have to try and relax and get focused again."

Asher-Smith helped the GB 4x100m relay team to a new British record of 41.81secs as they stormed to victory in the opening event of the weekend on Friday.

She followed Asha Philip and Desiree Henry before handing over to Daryll Neita and the Orpington ace admitted: "The third leg was a massive change for me. It was such good fun. I was watching Daryll down the last 100m, I could see the time counting down and just thought, 'oh my God, we are going to do it'.

"To run the British record is sensational."
