before 2007 Usain had some troubles with injuries and he had a plateau of performance
he is a freak of nature but he had (with his new coach, Mills) change his plane of training
You have changed a hand timed formula that has worked reasonably well for hundreds of athletes over a lifetime, working backwards to coincide with what Bolt has run versus what he could run optimally.
I am certainly not the only experienced coach who is convinced he can go much faster over 200m.
If your theory worked, MJ would have run 19.96 at best.
I think conversions are a crapshoot and speculation is sketchy (especially when you’re talking about a talent as mercurial as Bolt)
but there was a reasonable headwind
and it looks like the rounds really cut into the last 50 of that race.
I don’t see why a sub19 on that race is so wild a counterfactual, if we imagine away a few of the factuals.
There’s no real precision (and I can’t stand the bold statements of the kind “This was a 9.611256 BASIC!!!”) in this but if we’re just talking about a range, 19.0 doesn’t seem so out of the question.
I just did a quick and dirty, back of the envelope analysis on the relationship between the 100m and 200m using the top 250 100m/200m/400m athletes of all time and came up with:
Estimated 200mt = -1.0634(100mt)^2 + 22.835(100mt) - 101.92
This gave Bolt 19.24 based on 9.58 and 19.34 based on a 9.62
Tyson: 19.54 based on 9.71 and 19.67 based on 9.77
Obikwelu: 19.85 based on 9.86
And my own PB within 1/100th of a second.
It predicts that Bolt would require a 9.48 to break 19 seconds.
The model goes out the window, when you look at guys that were predominantly 100m runners and only occasionally ran the 200m (over estimate) or vice versa (under estimate), this could be because they never maximised potential in one or the other.
Before I cop a heap of crap for this and get smart alec remarks about a correlation between the number of bolt and his reaction time - I know it’s rubbish, but its a bit of fun and least this one doesn’t pretend to be deterministic.
The problem comes in when we try to forsee what’s possible versus what people usually get, especially when execution is less than perfect- something even Bolt brought up today.
We already know what everyone’s done so far.
i stand by my prediction of sub 19 as possible this year.
Just wait Charlie, he will. The first thing Usain said to Spearmon was “I’M TIRED. I’M SOOO TIRED”.

19.65 – 9.96
xavier carter double his best 100m = 20s then take away 0.37
19.63 – 10.00
Here are just a few examples of some athletes with 200 and 100m times.
MJ never really ran a 100m - his time is from 1994.
Wallace and Xavier - 0.27 and 0.37 Faster than doubled 100m are really the only indicators that one can run faster than doubled 100m times. And Maurice had the opposite factor!
Ato, Carl and Usain are almost smack dead on double.
If one had to predict an athletes 200m time, i would do the maths on the Individual - Otherwise, using the guys up above, we get a time ranging from
19.44 (maurices range)
to
18.36 (MJ’s Range)
or 19.16 (Carl n Ato n Usain current)
or 19.28 (crawford n gay)
or 18.76 (xavier)
or 18.89 (wallace) - Wallace is the only guy who’s MATH even comes close to the 0.24 formula. Xavier is almost but thats it.
Then like some have said, are xavier and wallace known to run the 100m as aften as the 200m???
The more one puts into the 100m, the more the difference becomes closer to simply Doubling 100m??
Like I said its just a quick and dirty prediction based on less than ideal data that I put together for a little bit of fun. The thing to keep in mind about statistical models, is that they are only as good as the assumptions made. Also the dependent variable, in this case 200m time, is only an expected value not a limit. I’m sure that if I put in a prediction interval, the range of times, (either side of the predicted value) it is likely to encompass would be wider than I would like to make an accurate forecast.
I don’t discount your sub 19 prediction, but then again I also wouldn’t discount an improvement in his 100m. With sufficient rest, this week must have provided some serious training stimulus.
The big question now is, where does bolt go from here? Other than breaking the 19 and 9.5 second barriers and continuing to lower his own WR each year and moving towards the frontier of post race clebrations, he has achieved almost everything on offer to him and the 100m and 200m. Will Bolt get bored and move up any time soon?
Bolt was relatively fresh in Berlin for the 100 but not for the 200.
If Boldwarrior is right, Bolt won’t go under 19 till he breaks the 100 significantly. If I’m right, he will. We’ll have to wait and see.
Frank Fredericks double his best 100m = 19.72 then take away 0.04
19.68 9.86
walter dix double his best 100m = 19.82 then take away 0.13
19.69 – 9.91
michael marsh double his best 100m = 19.86 then take away 0.13
19.73 - 9.93
All Bolt needs now is 1x200m at a grand prix meet with 1.5-1.9 tail wind and being really inspired to run flat out. Not only he would go sub 19 he would run in 18.65-18.85 range.
That’s assuming the rounds only have a negative effect on performance. No doubt they have a negative net affect, but there may also be positives that mean it’s not as pronounced as it otherwise may be.
It worth noting the last 5 WRs have been run under championship conditions with the last 3 the athlete has doubled.
So you can see him improving half a second more and beating Tyson by 10m?hmm

Dazed
Without a doubt, I can.
According to the above posted splits Bolt did 9.92 (being tired from the rounds mind you) and 14.44.
If we remember that he did 14.35 in Manchester this is giving us an indication that Bolt could go faster then 14.44 or 14.35 when in peak condition. I reckon he can go 14.10-14.15 over 150m. If so and with 1.5-1.9 m/s tail wind deduct another .20-.30 to his time. And if he runs the first 100m in 9.85 (which he can easy) we will be looking at substantial sub 19 with or without Gay behind him. Gay can not get close to Bolt in the 200m
As I said, in peak form, one race only, ideal weather conditions and especially if Gay is in the race, Bolt will fly.
In respect to distance between Gay and Bolt, if Gay was to run his best 200m I think he can get down to 19.35-19.40 (chasing Bolt) - so perhaps it would give Bolt 6-7-8m winning margin.
Negatives
- 8th race
- head wind
- did not specifically train for the 200m
- no Gay in the race
- perhaps the track to certain degree
Turn this into;
- 1 race only
- 1.5-1.9m/s tail wind
- train for the 200m as well
- Gay in it
- fast track
- good financial incentive
RESULT - an amazing time!
BBC news;
Bolt set a time of 19.19 seconds to demolish the previous record of 19.30 he set in winning Olympic gold last summer in Beijing.
The 22-year-old finished well clear of the field, with silver medallist Alonso Edward finishing in 19.81.
Wallace Spearmon of the United States took bronze.
Bolt, who also smashed the 100m record in Berlin on Sunday, is now the first man to hold the 100 and 200m world and Olympic titles at the same time.
And, the first ever to break WRs in the 100m and the 200m events in the two consecutive championships. I can not think of it right now but who was the last to hold WR in those two events at the same time? Plus, the fastest ever over 150m.
So, I guess 300m and 400m WR may be next (or a few years away) on his agenda.
Talking about GOAT - he is GOAT.
Wow, amazing…he did that with a headwind…He’s a freak of nature. It was expected of him, but he did it.
He broke records in the rain and made a 9.71 look easy.
He made 19.5 look easy in rain.
Yes, we wanted to see a sub19 but doing this into a headwind is amazing.
I think it’s a hell of a lot harder to run 100m around a curve than it is on the straight. I also think giving Bolt an outer lane will help lower his times. The reason I think this is he knows he will win, he’s so much faster than everyone anyway that he isn’t using people he can see to judge his pace, and this minimizes the effects of the curve.
In ‘The Lore of Running’ by Tim Noakes you’ll find various tables which have used different statistical methods(!) to predict the progression of performances over time and interestingly…ultimate performances for 100m to marathon. If my memory serves me well, the ultimate performance prediction for 400m was 39secs
Vabo, Mills is Usain’s coach from late 2004.
