Usain Bolt 9.58s WR 100m
 

World Champs in Berlin...

Seems around what he probably would've gotten in Beijing...

Tyson Gay ran a 9.71s and it seems like he's 3-4m behind Bolt haha. So sick.

And 10.00s 100m only gets you 6th place. :p



edit: he does slow down a bit at the end... looking to the side for Gay + scoreboard

edit2: I think his Beijing run was a bit better actually

Dude eats a lot of chicken mcnuggets.... -_-

Must be the McDonalds!

No way was his Beijing run better. It might look better because no one else was as close as Gay was in this race, but the numbers speak volumes. Bolt's 10m splits in Beijing were:
0- 10 1.85
10- 20 1.02
20- 30 0.91
30- 40 0.87
40- 50 0.85
50- 60 0.82
60- 70 0.82
70- 80 0.82
80- 90 0.83
90- 100 0.90*

Last 10m slow due to celebration. The last 20m of the 100m is deceleration. His last 10m might've been 0.85 in Beijing had he not celebrated, giving him a 9.64. You could argue up or down .01, but his last 10m split would've had to be 0.78 to run what he just did. Not happening. This is his best run to date.

Gay was no more than 4' behind him, which holds for the difference...figure about 0.1 seconds per meter in the 100m, give or take. 10m splits aren't available yet for this race...still too early. I'm betting his reaction time is markedly better and you'll probably see a slight decrease in some of his 10m splits. He looked faster out of the blocks...in Beijing he was last out of the blocks. This race he got out about evenly with everyone else and got his boogie on.

Progression of 100m WR

Thanks for the analysis Scott. :p

I'm interested to see his 10m split times around the 40-80m mark this time around, and his start/finish. That would give the indication of what he was/is doing and if he has anymore top end speed left

The real scary part:
a) He's only 22 years old. Sprinters typically peak in their mid-late 20s.
b) He's only been running the 100m for a couple years and is just figuring out how to get his unorthodox body through that race.

How fast can he go? He claims <9.4.

Wow, he split 1.61 in 60-80m which is average of .805 which is faster than the .82 10m splits in the above Beijing final.

.805s 10m split translates to 12.42 m/s or 27.79 MPH

He saved about .02 just from his reaction time. The wind helped him out another 0.4 seconds. And back to the scary part, some analysts are saying, while his technique has improved, he still has much to go in the first 30m of the race and was the worst technically in this race. Scary indeed!

He averages over 23 mph. My estimated top speed is about 23.5 (avg 19.96). Dang dang, that'll make ya feel slow!
