I expected a little faster but the race is what it is. Usain Bolt was straight into the lead and never relinquished it. This was a quality race. You could not separate the guys for bronze.I don't think Adam Gemili could have done more to get that bronze. If you look at his race and his position, he finished ahead of guys like LaShawn Merritt.

Usain was so aggressive out of the blocks. Andre de Grasse said he wanted to go with Usain and that is what he has done. If I am honest, many of the athletes will be disappointed with their times.

My heart goes out to Adam Gemili. To be fourth with the exact same time as third place. Adam will be devastated no doubt but he is still fourth in the world, he has to remember that and he has a bright, bright future ahead of him.

If that is it, if we never seem him again in a 200m final it will be a real shame, what on earth are we going to do without him.

Would you believe it - it's another FOURTH for Great Britain as Adam Gemili is pipped to bronze by Christophe Lemaitre.
They clocked the exact same time.
Andre de Grasse was second.

Usain Bolt wins it with absolute ease - but he is ANGRY! It's only 19.78, the same as he ran in the semi. He wanted more.

Here we go indeed. It's the end of a sporting era in a way. Can Usain Bolt bow out of individual Olympic sprinting with a world record?
Jo Frazer-Wise: Quite pleased to be awake to see Usain Bolt - he does make an #Olympics, external special

The Olympic stadium is as full as I have seen it. How fast?
Men's 200m final
Last night Usain Bolt said that he would run in London at next year's worlds - but only at 100m. So this is likely to be his last ever 200m in a major final.

Olympic heptathlon gold medallist on BBC TV
This is a foregone conclusion. Bolt should and will win this. He looks very relaxed, this is such an important event for him. He wants to dominate it and dominate it big.

As chilled as ever. Usain Bolt strides out to the starting blocks, waving to the crowds on the way.
Usain Bolt won in London in 19.32. In Beijing in 19.30.
