Reaction from Usain Bolt and 10,000 metres world champion Mo Farah at the IAAF World Championships in Beijing, China on Saturday (22nd August).

Script: SOUNDBITE: (English) Usain Bolt, Jamaica:

"Happy with my execution and my performance. I am just looking forward to tomorrow. And looking forward to getting it done."

2. 00:08 SOUNDBITE: (English) Usain Bolt, Jamaica:

(On Gatlin's fast time):

"We all ran as fast as we need to go and that is pretty much it. In the qualifiers you are trying to get there as easy as possible and as relaxed as possible so it is just one of those things."

3. 00:19 SOUNDBITE: (English) Usain Bolt, Jamaica:

"It was good. I would probably say 70. It was pretty good. It wasn't as bad as London so I am happy."

(question: And you had a smile at the end. More to come?)

"Yeah definitely"

SOUNDBITE: (English) Mo Farah, 10,000 metres winner:

"Yeah. The race was really exciting. I knew from the start that it was not going to be easy. They guys worked as a team and I knew that was going to happen. So it was a matter of just staying at the back and staying out of trouble. A couple of times I nearly got tripped up but thank God I didn't get tripped up. And I managed to stay on my feet."

5. 00:46 SOUNDBITE: (English) Mo Farah, 10,000 metres winner:

(question:. How important is Alberto Salazar in this gold medal?)

"It is the whole British team to my success. Neil Black. Barry Fargan. Everyone who supported me and it hasn't been easy but as an athlete I love what I do and I love to run and represent my country and I just carry on running and that's what showed tonight! I just just keep have to going on that and keep smiling."

6. 01:03 SOUNDBITE: (English) Mo Farah, 10,000 metres winner:

"For me, I would have loved to have seen my family here but unfortunately not because my wife is expecting. It hasn't been easy. I've just got to keep doing what I am doing and get ready for the 5K!"
