Fastest Negative Split 800m?

well i know for a fact that 55,54 is possible. my teammate ran a 1:49 running those exact splits at the end of last may.

On the "no way it is physically possible" bit -

I'm fairly certain that since Wilson Kipketer ran 48/53 (and change) he could have easily run 55/54 had he so desired.

The olympics this year were something like 53/51 for 1:44, and when Steve Ovett won it was something like 55/50 for 1:45.4 with Seb Coe closing in around 24 mid for 2nd.

First of all, you could have gone 1:51 had you not gone out at 1:46 pace. If the first lap is over 4 seconds faster then the second, you fail.

Many heats and semis at the world class level go out in 54-55, and everyone negative splits.

But to answer your question, Cram ran 1:42.88 with 52/51.

Oregon high school junior Elijah Greer ran at least three 1:50.xx races this year with first laps of 55.xx. If he can do that, I have no doubt there are all kinds of elite guys that can run 1:49 off a 55. Just looking at the Olympics in the 800m heats, in Heat 3, the leader went through 400m in 55.90. 6 of the 7 finishers ran between 1:47.61 and 1:50.67. In Heat 7, the leader was 54.69 at 400m. Three finishers ran 1:46.94 and 6 guys were between 1:46.94 and 1:48.19. Andrew Wheating ran 1:47.05 and I'm pretty sure he was over 55 at the bell.

Your friend is an idiot. Milers close in 1:50 with negative splits in just about all of the championships races these days. I can't remember Cachos splits exactly but he was something like (57/50). Morceli was like (55/53). 1:50 just isn't that fast these days.

I bet Nick Symmonds can do that.

I am trying to settle a bet. What is the fastest you can negative split an 800m, quarter split only. My friend claims that there is no way it is physically possible to run sub 1:50 and negative split (55, 54). I believe that there are a few world class guys out there that can do it. But even these guys run consistently slower each 200m as the race progresses.

The fastest I have negative split an 8 is 1:57 (59,58). My PR is 152 (53,59). Out of curiosity, what is the fastest you've negative split an 8?

what's with all these retarded threads? the "any chemists" thread that's asking how to find the area of a square, the thread about how to find the average of 8 mile times, and now this. Of course there are "a few world class guys who could do it." There are a lot of guys who could negative split sub-1:50. You don't have to be world class to be able to do that. To answer your original question, I wouldn't have put it past Kipketer to neg split a 1:42, but it would be a tiny negative split

Nils Schumann did a negative split to win in Sydney. That is a fact. First split was 53.43 by Longo (bastard) or Bucher. Winning time was 1:45.08.

My friend is an idiot. I knew it was possible, now I have the proof. Thanks.

Jim Ryun: 53.3/51.6, 1:44.9.

For 880 *yards* (about .7sec longer than 800m).

Two hours after running ~1:51 (? IIRC?) in a prelim for the event.

Is it safe to say Nils Schumann was not doping? Apparently he comes from a town with the coolest name ever, Bad Frankenhausen.

Okay, so the fastest so far is 142.88?

In case all those others turn out to be bunk, I'm throwing my 60/54 out there for good measure. Did it twice.

My time wasn't sub 1:50, but I ran a 1:57 and change with splits of 64/53. It was on my third 800m race. I always ran negative splits on my 800m. Usually my last 200m were under 23 seconds. I always had a habit of going out too slow. I've done 88/52 before as well, that was my largest negative.

The closest I came to running non-negative splits was when I was puking before the race. It was state qualifications (I blamed it on something I ate, but I was probably nervous). I ran 67/66 and got pissed at myself after the race... All I needed was a 2:04 to qualify for state... I know I could have run harder.

My 800 Pr was run with positive splits of 57-64...is that good? loll

Sorry, Ryun wins.

Yeah, that is a good time. Not many people can run a 2 minute 800m. You will need training in order to do that.
