Rudisha time predictions for 100m through marathon

One thing you have to realise is that the 800m is an extension of speed. Without sub 11 capabilities you wont run a 1:41.xx. Essentially with your logic one can sprint an entire 400m virtually flat out. And lets face it, that makes you look pretty silly.

You fail to realize that the 800m is NOT a 400m. What part of that are you not realizing? Obviously you need speed to run a fast 400m but you absolutely do not to run a fast 800m.

You're basically forgetting that 100m to 400m is only an extra 300 meters. But 400 to 800 is an additional 400m extra. A huge difference in anaerobic/aerobic usage.

Look at the charts again. The 800m is roughly 25% anaerobic. Not much need for sub 11 sprint speed there.

You're also failing to take into account that the start becomes absolutely pivotal in the 100m dash. This is not a 400m run where you can skip out of the blocks and be okay.

Even with a modest time of 11.5 Rudisha can achieve a 1:41.

11.5 x 8 is equivalent to a 1:32. Are you really that "silly" to believe that he's sprinting flat out because he can only run 11.5?

What is wrong with you people. I personally have run 1:53 open and 11.33 from blocks (yes the same season - within weeks). I am primarily a 1500 guy. Is everyone you know slow as hell? I know tons of people who have broken 11 out of blocks who are 800 specialists.

Let me guess - do you also think that lebron can run 10.5 because he is 'athletic'?

laughable!

I call Bs. If you run sub 47 training for 8's youd have a stable of juniors in the olympics. And they wouldnt be running 10.9. Youll only go sub 11 as an 800m guy once you go sub 46.

The 800m is 55% anaerobic. But you dont even need to use the 800m because he has a 45.5 400m that we have to use. Further we have a 33low 300m in that same race to use. And that 300m is two bends + one straight as part of a 400m.

1:41 off 11.5. Lol you must be trolling. Even with all the epo in the world you would struggle to crack 1:46. 11.5 and you almost guaranteed not to break 48 for the quarter. Thats 92% of his supposed max over 800m! Even more phenominal thats 101% of he max over 400m. My god not only can he run flat out over 400m but he actually gets faster!!! I want what hes on.

Wins the award for the most absurd post in lets run history... And I thought people couldnt get more retarded. Lol

Hahahahahahahahaha sooooooo stupid....

100m: 10.7

200: 21.2

400m: 45.4

800: 1.41

1500m: 3.34

3000m: 7.52

5000m: 13.55

10000: 29.50

My god you're an idiot. You realize that the next 100m splits in a 400 are flying splits right? Not standstill splits. Throws your theory of 101% garbage out the window.

I think you all are absolutely correct in he can go 10.7..... with a flying start. I'm 100% sure he can.

But not out of blocks. Not from a standstill. And don't tell me "if he trained for it..." that's nonsense. Let's take him as he is now and see what he can do.

Find me one example of someone who has run 400m faster than 94% of his maximum 200m time.

Or find me a 400m runner who goes through 200m in 21.9 virtually flat out and still finishes the last 200m within 92% of his best 200m time [Which you deduce is 21.7].

Better yet find me a 200m from anywhere in history where someone who only runs 11.5 out of blocks is capable of running 21.70 let alone 45.5 in base!!

Lol even at your own reasoning if he runs 21.7 he is not going to be running your estimate of 11.5 over the first 100m seeing as its a bend. So if he goes 11.7 for the first 100m he is running 10.00 for the second flying 100m.

Now genius find me anyone who can run 10.00 flying yet cannot break 11.00

Are you immune to logic??

Have you heard of speed reserve. Do a google search before you keep embarrassing yourself.

Please go back to my original post. And my original stance. I said Rudisha CANNOT go sub 11.

In fact, this 11.5 was just an arbitrary number that came up just for reference purposes. I originally stated that i thought he would run an 11.2 in the 100m dash.

Then i surmised that a sub 22 MIGHT actually be plausible for him given how the 200 is less dependent on the start. I said 21.8

I imagine Rudisha's splits in his 45.5 to be...

11.8 first 100m:

10.8 second flying 100m

10.9 third flying 100m

12.00 last 100m

For reference MJ's were:

100m: 11.10s (11.05s)

200m: 21.22s (10.12s)

300m: 31.66s (10.44s)

400m: 43.18s (11.52s)

It may be strange that his third 100m split is so close to his 2nd. But i find it correct in that he hasn't hit his full running until 75 meters due to his difficulty accelerating and atrocious block start. It seemed like he was going all out the first 300m and figured he could hold it because of his 800m background.

MJ had superb acceleration and could lock into a certain pace very quickly in the race.

21.8 is 96% of his max speed over 400m. Clocking 21.9 for his first 200m is flat out. Now if he was actually flat out for his first 200m his lactate levels are higher than at the 600m mark of an 800m. So if he can produce a 2nd 200m off a rolling start of 92% of his max under severe lactate he shouldn;t be coming home in 25+ seconds in an 800m.

His speed reserve is why he came home in 23.6 seconds in his 400m that day. 21.9 wasn't flat out for him, 21.1 is flat out and for that reason he was able to maintain a decent differential rather than completely crumbling.

Further the 45.5 he ran was in Sydney during his basic preparation. He had not touched speed work.

You can't really even use 45.5 for reference. He was obviously under 45 when he ran 1:41.01 considering the 45.5 wasn't during peak comp season.

Body Master!

So we have 6.78 and 7.50

Anybody else care to guess what Rudisha would run for 60m?

Wow, somebody on this board who actually seems to know something about sprinting. Who would have thought? Body Master!!

Come on guys, I know you can do it. Somebody can bid better than 6.78

60m times, we need to hear them! Do I hear 6.76?

I doubt you and your alter ego wont get replies. Everyones to busy laughing at you...

No one cares about 60m. Its an irrelevant distance in relevant competitions. http://www.sprintic.com/training/training_for_400m/ for your education...
