Tyson same 80m like Ben in 88…
IMHO this is just way too lopsided, I’m bored! It was more interesting when here were several guys always barely scratching .01 off the WR and it was competitive, knowing who will win is no fun.
Exactly! And prooves my point about how fast Ben could have gone if he hadn’t shut down like he did. I’m certain he would have gone 9.73to 9.72 then and I was criticized heavily for saying so…and with a faster surface??? Maybe a bit more.
But now with 9.58, that ship has sailed! I’m still not entirely convinced that this track is the best ever for the 100m but the additional resiliance may alter the relationship between 100 and 200 more in Bolt’s favour for the longer sprint and it leaves more in the 100 for next year.
I hope he doesn’t go for the 400 next year because the record is so inferior to either the 100 or 200 that it doesn’t seem to matter.
We already know MJ could have killed it if he hadn’t been injured in 1996. Changing his training now might make it hard to get back to where he is now and he might need to break 40sec to go where he will be by the end of this week in the 200!
I just read Speed Trap and enjoyed it (though I wanted to know more about your relationship to Ben beyond the funny anecdotes). I agree with the projections above and in the book - somewhere between 9.76 and 9.71 for that particular race and faster with other factors.
So, with the projection game in mind
let’s say Bolt had another m/s of wind
is that in the 9.49-9.51 range now?
AND let’s say Bolt was at altitude
is that in the 9.39 - 9.45 range now?
let’s say he peaks somewhere between the age of 25 and 30 and shaves off some more time at that point
9.36-9.42 in some sort of perfect confluence of legal factors?
My ranges are obviously sort of arbitrary (mainly because I don’t know THAT much about track) but I’d like to hear some knowledgeable folk way in on the “perfect world” scenerio.

an extended analysis of the race with graphs
Hard to play the wind game too effectively but:
Lowest humidity
Highest allowable tailwind
High temperature
Altitude like Mexico City or Colorado Springs
all combined with the same or better track surface and you’re into the 9.40s.
And that’s with him as he is now.
God, it’s bizarre to even be having this conversation!!
Since 1968 we’ve seen the world record in the 100 drop by almost .4 ( 9.95 to 9.58 ) but 30 meter block values seem stalled out at 3.78-3.80.
What might explain this? Are the athletes getting more from the track from 30-100? Have 30-100 training methods improved that much?
I think that we want high humidity, though I’m not totally sure. I do know that humid air is less dense than dry air. I’m not sure what other effects the humidity might cause.
Unless that is a misprint it appears Gay actually re-accelerated after 80 meters. Very unusual. But I am not sure I understand the chart here. It says he went 70 meters in 7.21, and 80 meters in 8.02. The difference there is about .82, however the 80 meter time reads .85. Am I misreading things?
0.85 is between 80 and 90m…
.81 for 70-80, .85 80-90, .84 90-100m according to those numbers. The time next to the 80m time is the 80-90m interval time.
If it is easier look at it this way;
20m - 2,92 -
30m - 3,83 -
40m - 4,70 -
50m - 5.55 -
60m - 6,39 -
70m - 7.21 -
80m - 8.02 -
90m - 8.87 -
100m- 9,71
20m 0.91 30m 0.87 40m 0.85 50m 0.84 60m 0.82 70m 0.81 80m 0.85 90m 0.84 100m- 9,71
The smaller the distance the smaller the time diff but there was a big drop in 30 times when Ben ran 3.80 in both Rome and Korea. These times had never been approached before but after 1991 with the new track surfaces they became more common with some times under 3.80 but many times at or around it in recent years.

While talking about the results Ben ran in 30m…how fast did he run 30m from a standing start (in training) HT?
Thanks
He ran 40y in 3.7 so you can guess (3.1?)
I believe oxygen concentration [breathable gases] decreases with humidity because the very same volume is filled with “gasified water” and there is less space for “air” molecules, BUT volume density of the gas you breathe increases because in the very same unit there are heavier molecules than before (moisture vs. gas). Oxygen / nitrogen and other atmosphere gases rise to give place to heavier H20 molecules. That way the atmosphere becomes more viscosius and it requires bigger forces to move arround in it.
Am I wrong?

Thank you!
Check out this poorly made graph, its bolt 09 vs bolt 08. The difference is really from 60-100m, do you think if he didnt ease down he could have run that in beijing?
It is interesting to note that both Gay and Powell ran the same times at 40m, 50m, 60m marks;
40m - 4.70
50m - 5.55
60m - 6.39
Powell was ahead of Gay at 20m, and 30m. The biggest drop in AP performance was at 80m mark.
