That concludes the 100m heats. We'll have the final semi-finals list updated shortly.
21:22 (IST)13 AUG 2016
South Africa's Akani Simbine finishes first with a time of 10.14 and Japan's Ryota Yamagata barely finishes second ahead of the rest with a time of 10.20.
21:20 (IST)13 AUG 2016
The athletes can't concentrate because of the buzz around the stadium after Bolt's race. Understandably so and they're taking their time to compose themselves.
21:19 (IST)13 AUG 2016
We're all set for the final race to wrap up the 100m heats!
21:17 (IST)13 AUG 2016
It's almost hilarious to watch the rest of the pack trying to catch up to Bolt who was clearly running at about 75% towards the end.
21:15 (IST)13 AUG 2016
While the rest try their best to win the heat, Bolt starts slowly and literally jogs to the finish line with long strides. Usain Bolt wins with a time of 10.07 while Bahrain's Andrew Fisher finishes second with a time of 10.12. Interestingly, Bolt had the second-slowest reaction time at the start!
21:13 (IST)13 AUG 2016
Bolt asks the crowd to stay silent and you can now hear a pin drop in the arena!
21:12 (IST)13 AUG 2016
Bolt is soaking it all in as he walks up and down the track while he loosens up. He sees the crowd too and acknowledges them in his trademark way as his name is announced. What a showman!
21:08 (IST)13 AUG 2016
And the crowd in Rio knows it too. The Jamaican champion walks into the arena to loud cheers from the crowd.
21:07 (IST)13 AUG 2016
Jamaica's Yohan Blake easily finishes first with a time of 10.11 while Turkey's Jak Ali Harvey finishes second (10.14). Blake started strong and never gave up the lead he got early on. Comfortable win and Blake gets the job done in the heats.
21:05 (IST)13 AUG 2016
21:00 (IST)13 AUG 2016
In the final lane, Ivory Coast's Ben Youssef Meite finishes first with a time of 10.03 and USA's Trayvon Bromell finishes second with a time of 10.13. Meite was looking over to see how far ahead he was and it was just a tenth of a second in the end!
20:57 (IST)13 AUG 2016
Look at how far ahead Justin Gatlin was in his heat in spite of slowing down in the last few metres.
20:56 (IST)13 AUG 2016
Canada's Andre De Grasse finishes first with a time of 10.04 and Japan's Aska Cambridge finishes second with a time of 10.13.
France's Jimmy Vicaut, who had the third-fastest time in 2016 before the Olympics, finished fourth with a time of 10.19! That will be a huge blow if he doesn't qualify as one of the faster losers.
20:49 (IST)13 AUG 2016
Five fastest times so far (after 3 heats)
Gatlin (USA): 10.01
Xie (CHN): 10.08
Ashmeade (JAM): 10.13
Kemarley (BRN): 10.13
Ujah (GBR): 10.13
20:46 (IST)13 AUG 2016
China's Zhenye Xie finishes first in the heat with a -0.1m/s wind and a time of 10.08s while Jamaica's Nickel Ashmeade finishes second with a time of 10.13s.
20:41 (IST)13 AUG 2016
It was a very comfortable win for Gatlin and the American even eased off towards the end. His time of 10.01s sees him sail through to the semis while Daniel Bailey of Antigua finishes second with a time of 10.20s.
20:38 (IST)13 AUG 2016
Gatlin is in lane 8.
20:37 (IST)13 AUG 2016
Gatlin is currently the fastest man in 2016 with a time of 9.80s. That will be enough to qualify in the heats.
20:36 (IST)13 AUG 2016
Remember, only the top two athletes from each heat automatically qualify.
20:34 (IST)13 AUG 2016
20:34 (IST)13 AUG 2016
Heat 1: With a wind speed of -1.2m/s, Bahrain's Kemarley Brown wins it with a time of 10.13s while Great Britain's Chijindu Ujah finishes second!
20:36 (IST)13 AUG 2016
Usain Bolt will have to wait a while for his heat.
Gatlin is in Heat 2.
Blake is in Heat 6.
Bolt is in Heat 7.
20:18 (IST)13 AUG 2016
Right now you can see the athletes warming up outside the stadium. Bolt looks very relaxed as he goes through his stretches while the same cannot be said about his compatriot Yohan Blake and USA's Justin Gatlin who look a little tense before the event.
20:11 (IST)13 AUG 2016
