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.

Some old posts (2006) on the same subject.
This list has undergone dramatic change as I have included split-times from Gatlin’s 9.77=WR in Doha earlier this year. Kim Collins’ 1.67 0-10m Minus RT is taken away as it was an estimate split-time that I gave for him in my 2004 Athens OG 100m Final Analysis
Also, with the inclusion of Gatlin’s new best time of 0.85 from 30-40m Mo Greene & Asafa lose their shares of the best split in that section

it’s really a bit pointless because the timing is in the 'eyes of the beholder" and i allowed the athlete to “commit” to an aggressive motion. I did this because I wanted the athletes to lean into the run before the clock started to encourage relaxation. A stricter timing means would quickly show the athlete that changing to a more abrupt start would yield better times over the short stuff and encourage tightness.
As long as I was consistent I could predict a block start E-time from there but others might get a much slower hand time.
In general, I would add .65 to equal an E-timed, block start over the distance, including the reaction time. That seemed to work pretty consistently for me and that’s why we were able to predict race times as often as we did.
I should have formulated my question differently. I was looking for this info;
In general, I would add .65 to equal an E-timed, block start over the distance, including the reaction time.
Thanks.
