OK, it’s not Michael Phelps territory, but Usain Bolt clinched his third gold medal and third world record from three events when Jamaica won the 4×100m relay on Friday.

Bolt teamed up with Nesta Carter, Michael Frater and Asafa Powell to clock a time of 37.10 seconds and take 0.30 seconds off the 15-year-old record set by the United States at the 1993 world championships.

There was disappointment for Jamaica, however, when their women’s relay team were disqualified for messing up the second changeover between Sherone Simpson and Kerron Stewart.

Still, five out of six ain’t bad.

Jamaica’s Usain Bolt completed a breathtaking sprint double at the Beijing Games on Wednesday, breaking the 200 metres world record that many had thought unbreakable to take his second Olympic gold medal.

The contrast between this and his winning run in the 100 could hardly have been more marked, as this time he gave it everything he had to go under the old best mark, Michael Johnson’s 19.32, by two hundredths of a second.

While Bolt had ambled through the final quarter of the 100, and easily lowered the world record to 9.69, this time he was grimacing with effort as he made for the finish.

There was no one within two, three metres of him as he dipped for the line, glanced over at the clock and leapt with joy as the clock stopped at 19.31.

That was soon rounded down to 19.30 - a mark that will surely not be bettered, certainly by no one else, for a long time to come.

It completed an incredible sprint double for the world’s fastest man and cast an indelible mark on the Olympics. None of us in the 91,000 crowd at the Bird’s Nest will forget it.

What did you make of his performance? What does it mean for Jamaica?

Let us know in the comments.

After the shock of Liu Xiang’s departure from the Games through injury, fans in the Bird’s Nest were given a golden moment to compensate at least slightly, as the peerless Yelena Isinbayeva broke her own world record in the pole vault.

The Russian made sure of the gold medal with just two jumps before returning to have a crack at raising her own best mark. After missing twice, she cleared 5.05 metres at the third attempt — with plenty to spare, it must be said.

There was never any doubt about this one. Michael Phelps won the 200m freestyle, secured his third gold medal of these Games — his third world record, too — and become only the fifth athlete to win nine gold medals at the Summer Olympics.

He joins fellow Americans Mark Spitz and Carl Lewis, Finnish athlete Paavo Nurmi and Soviet gymnast Larysa Latynina at the top of the all-time list of gold medal winners.

But the record he really has in his sights is Spitz’s haul of seven gold medals in Munich in 1972. Can anything now stop Phelps going on to win all all eight?

He certainly looks to be swimming better than ever at the these Games, with today’s time of 1:42.96 shattering his own world record by 0.90 seconds. It was an astonishing performance.

Can he manage five more?
