"It's difficult when you have back-to-back championships. Athletes have to come here and deliver because there's funding at stake, but athletes who impressed in Glasgow have come here and prepared themselves mentally and physically. The other nations have only had the Europeans as their focus all year. I think that's credit to the British team that they have been winning medals."

Olympic heptathlon gold medallist and BBC Sport athletics panellist Denise Lewis will be answering your questions on Friday ahead of a big weekend of action.

Who are the future stars of GB athetics? What does it take to become an Olympic champion?

We want to hear from you. Leave us your questions for Denise by commenting on the BBC Sport Facebook page, external and find out what she says at 16:30 BST on Friday.

Adam Gemili speaking to BBC Sport after winning his 200m semi-final: "It takes you by surprise how quickly you are winning. It's a very good track but championship running is about saving energy. I slowed down and I've got more to show.

"I'm still only 20, still relatively new and the more I do that the more I can contend for a medal.

"Everyone in the final is a competitor. Myself and Christophe are the quickest qualifying but I'll go out there and run my hardest."

"Adam Gemili was dominant from the beginning and ran a strong and accurate bend. He pulls himself away from the field, there wasn't an ounce of tension in his face and he's just able to relax.

"At the moment it's in his favour because Lemaitre isn't running good bends and that will make a difference in the final."

Will James Ellington be in the final? Nervy times as Ellington and Poland's Karol Zalewski, both vying for that final qualifying spot, clocked 20.52sec. The calculators are out. We will let you know once a decision has been made.

"Adam Gemili looked very comfortable. It won't be easy in the final but with that performance you have to say he looks like the favourite because Christophe Lemaitre is tired. He will have to run a good bend and put Lemaitre under pressure but I think he will take the title if he comes out of the bend in the lead."

Danny Talbot speaking to BBC Sport after finishing sixth in his 200m semi-final: "It wasn't a great race. I don't like to make excuses but I haven't really been able to train after the Commonwealth Games. I picked up a little illness and it's taken it out of me. I'm not in the shape I was two weeks ago."

"Who are we to criticise an athlete in supreme form? It was a look of almost disbelief that he is running so quickly and able to shut it down after 150m. It's supreme running, a great piece of sprinting from Adam Gemili.

"He's still learning how to run the 200m and he just seems to be displaying such confidence and condition. The head to head between him and Lemaitre will be a great one."

Confident. Intimidating. Impressive. Adam Gemili looks around at his surroundings with about 50m remaining and eases off to win in 20.23 sec. The Briton is through to the final but his team-mate Danny Talbot isn't as he can only finish sixth in 20.62 sec.

James Ellington speaking to BBC Sport after missing out on an automatic place in the 200m final: "I put myself in a good position but lost it myself. I dropped my hips when I came off the bend and I should have carried on doing what I was doing. I was trying to hold back a little bit and I wish I had pushed off a little bit more."

"James Ellington ran a superb bend. You see him in the relay running that third leg and I was thinking 'just stay relaxed' but he seemed to go backwards and that's the weakest part of his race.

"He trains hard and he's working hard, but it's just not happening when he needs it. He was so annoyed with himself because he knows he had a chance there."

James Ellington a smidgeon ahead of Christophe Lemaitre coming out of the bend, but the Frenchman closes him down and bursts through to win in 20.26sec. Ellington finishes fifth, which probably won't be enough to qualify (although the two fastest qualifiers will progress so there is hope).

Also through are Ukraine's Serhiy Smelyk (20.32sec) and Italy's Diego Marani (20.36sec).

Right then. Fast-twitch muscles are what's in order because the men's 200m semi-finals are about to start. Britain's James Ellington, looking nerveless as he is introduced to the crowd, is in the first heat, along with one of the favourites for gold Christophe Lemaitre. Ready? Set?

"In the javelin we went from Dave Ottley in 1984 to Mick Hill and Steve Backley we need the heavy boys to come in. They're all going to rugby now and we need them back."

Just a quick reminder, coverage is due to start on BBC Radio 5 live with Jonathan Edwards.

Qualification for the men's javelin final has finished and Antti Ruuskanen topped the standings with a 83.76m throw. Three Finns are through to the final and there was some slapstick during the competition, too, as Kim Amb's javelin arrowed his javelin into the 75m sign. Japes.

Lord Sebastian Coe is standing near the podium, psyching himself up to present the medals to the top three finishers in the women's 100m hurdles. He does a marvellous job - a kiss on both cheeks, a bouquet and a beaming smile. Up steps Tiffany Porter and the European Champion has a floodlit smile.

Jodie Williams speaking to BBC Sport after winning her 200m semi-final: "I just did as much as I needed to do. In the rounds, it's about conserving the energy. I really like the track so let's see tomorrow.

"Dafne Schippers is an amazing athlete but anyone's beatable and I'm going to be on that line wanting to win. Three Brits in the final, I can't complain."

David White:, external British women's sprinting is really going through a purple patch....go Jodie Williams.

Yvonne Holden:, external Loving this - three, yes three British girls in the 200m final.

Andrew in Streatham:, external My advice to Bianca is to go and sleep if she does not have any events tonight. Rest the body.

"The British women just make this all look so easy, like they're meant to be here. Jodie Williams is still only 20 but she's running like a champion.

"The work she's done over 400m has increased that speed endurance and it's paying dividends in these championships. She's gone into a different stratosphere with her sprinting."

Such is Jodie Williams lead after a superb bend, she can ease off the throttle with 30m remaining and still effortlessly win. The 20-year-old is through to the final with a time of 22.90 sec. Second was Jamile Samuel (23.18 sec) of the Netherlands.
