Sub 1.41 - how can it be done...

Look like you done answered your own question boy!

by your math we are talking about sub 140, not just 141... dont get ahead of yourself

if you use 2s lap differential as "ideal" & i've seen a stats report which suggested each succeeding 200m shoud be 0.5s slower than the last, then you shoud be looking at :

24.5

25.0 ( 49.5 )

25.5 ( 1'15.0 )

26.0 ( 1'41.0 )

if you use a 2.5s differential ( which may be possibly better for a primary 800/400 guy rather than a 800/1500 type ), then you need 0.625s difference between succesive 200s :

24.32

24.93 ( 49.25 )

25.56 ( 1'14.81)

26.19 ( 1'41.0 )

oh yeah sorry, a typo - should be 26.6. Closing out in under 26 would seem to be virtually implausible at that sort of speed. Just goes to show how hard a sub 1.40 would be. Cheers.

Nice analysis, but you're asking a lot for a 4th 200 in 25.x. Rudisha just finished in 27 for his 1:41, though his 3rd 200 was maybe a little quick at 24.x.

I'd say the time has to come from the first 200 (23.5), and then hang on a little better than Kip when he opened in 48.6 for the 1:41.24.

Thrilling that we're even contemplating these possibilities for someone, after such a long wait from '97.

Step 1, Run a 24.2 for 200m

Step 2, Repeat step 1, 3 more times

yeah sorry, that was a typo - should have read 26.6 not 25.6. Yeah even closing out in under 27 is unfathomably hard given a sub 1.15 600m split but this is just what is going to have to be required (because holding on off 1.13.XX at 600m would appear highly unlikely) and just shows how difficult running 1.40.XX will be.

I knew youd show up. You are so good at this.

no human will break 1.40 - not in our lifetimes anyway.

Calling it close to the human limits in the 800m is simply an insult to the human race.

Even though Rudisha and Kipketer are different athletes (obviously) it is becoming clear that the splits for low 1.41 performances from these guys will be very similar. This level of running is obviously close to the current limit of human limits in the 800m.

eeehhhrrrmmm why?

Looks like Kipketer showed the way to do it was 24, 25, 25, 26.9 It would be nice to see a negative split performance though- maybe 25,26,25,24.9...?

Just curious- what is the fastest ever negative split 800?

borza probably ran -ve splits in his 1'42.4

next one was probably cram in 1'43.2

of course ryun ran a 1'44.3wr of -ve splits

just run wabbit run

It seems that the guy who runs under 143 usually has little competition at that stage of the race and is pushing from personal drive.

Therefore, I say we send a rabbit out in 1:14.xx for the first 200 and then provide a competitive figure for the guy trying to get under 141. the rabbit could DNF at the finish line.

I think that to PR in 800m the first lap should ideally be faster than the last. Like, you aren't going to set a 400m WR by running every 100m at even pace, therefore, so does the 800m, I guess.

Borzakowski 1.42,47(51,0+51,5),Kipketer 1,42,77(Monaco,16.08.97) 52,0+50,8,last 200m 24,6

The IAAF have Kip's Monaco run as laps of 52.3, 50.5! So which is right?

I find a 24.6 last 200 in a 1:42.8 (600m in 1:18.2) quite unbelievable. If that's true then the EPO must have been working real good that year.

My splits are right. Taken from good quality video. Kipketer broke three days earlier WR, so he was in fantastic shape. Compare Kipketers splits to Coe's

Stuttgart race. Coe's time 1.44,50 was in fact worth

c.1.43,3, because he run about 9m extra. His final

200m was 24,8,which included 3m exta. That was worth

24,4-5. So I find Kip's splits quite believable.
