Bekele's 5000m World Record by the numbers

Bekele's what?

I don't know. I still think Bekele trumps Komen if they ever race a 5000.

Bekele's 5000m world record.

kennster ran 1.88s faster than komen's ole 5ki wr

that was in kennster's 12'37 year

kennster ran his 5ki wr off pretty decent splits iirc

( someone dig up kennster's splits in his 12'49iwr )

komen ran his off a jog to 3k - 7'47+ - 12'58 pace but smashed it down to 12'51 on tight indoor bends which cripple speed

that komen was possibly good for

~ 7'17 / 12'32/12'33

Komen was incredibly even but still negative split.

Geb was uneven at first but a big negative split from first 1K to the last 1K.

Good evidence that negative splitting is effective and maybe optimal.

No doubt in my mind that negative splitting is the optimal strategy to maximize performance.

Of course that doesn't go well with "To give anything less than your best, is to sacrifice the gift" , but then again it depends on your definition of : Giving your best...

Shouldn't he have looked a little winded after that effort? I've been more bent over after a track workout. Makes you go "hmmmm".

Any mind worth having has doubts about essentially everything.

Do you have some sort of absolute proof? Or are you just more comfortable without doubts creeping into your mind?

bekele was the GOAT

presumably you're not

i think that explains it pretty well?

kennster also ran 5k/i/wr off 7'47 & nearly 2s off komen, but nice even splits to 3ki'm not sure komen had same luxury...

SPLITS

Split Athlete Nationality Time Kilometer

1,000m Michael Skinner Great Britain 2:35.83

2,000m Timothy Kiptanui Kenya 5:10.75 2:34.92

3,000m Kenenisa Bekele Ethiopia 7:47.27 2:36.52

4,000m Kenenisa Bekele Ethiopia 10:18.98 2:31.71

Finish Kenenisa Bekele Ethiopia 12:49.60 2:30.62

His 8 fastest laps would be ~ 8:02-03, why did he never try to break 8 in a two mile?

I believe he tried once or twice, but yes, he definitely could've in his prime. While Komen is probably #2 all time over the 5K (despite a #3 time), I still think Bekele could've beaten him in their respective primes, although obviously not at any distance less than 5K (2.5 miles even, for instance). I think Bekele's strength would've won out. As Vemt himself says, Kenenisa could've gone faster in that WR if pushed.

It'd be DAMN close, though, and this is just my opinion obviously.

Yeah, 'cause speed-based guys are so much better at handling early oxygen debt and grinding it out under fatigue.

I think stronger runners are more likely to PR this way while those that are more speed based need to get out quicker and maintain.

Speed based guys (someone with a faster 1500m PR in this case) would have an easier time with a fast start.

Simply put, the first 1500m would be easier for them. The remainder would be easier for the strength guys.

So a speed based guy would need a faster start to run the same time.

Look at the 800.

The 400/800 types go out faster and hang on.

The 800/1500 types run closer to even splits.

See Robby Andrews vs. Charles Jock for the best example.

Anybody who gets near that record has speed-side

Wrong. Anyone who gets near the 5K record is probably an ideal 5k runner.

A 'go out fast and hang on' for speed guys only happens in the 800 because of the use of energy systems and NOT because speed guys should over pace the first half of every race. Dont confuse this.

In a 5k you can never run your fastest when the first mile is the quickest.

I agree that a 57 last lap indicated a potentially quicker time, especially for Kenenisa but it was a world record and in track there is no 100% perfect race but 12:34/35 was 'possible'.

Komen with perfect pacing is at the same time, for Haile i think he was at his limits and could not match Daniel and Kenenisa at 5k.

Haile ran his last 1600 in under 4 minutes...

I'll say that in my 5K PR my first mile was the quickest.

I don't know how many others here would say that.

I was an 800/1500 runner.

If I worked more on developing my 5000 or just raced it more and got stronger my ideal splits would become more even and maybe negative.

I looked up Aouita's 5000m WR when he ran 12:58

2:35.4

2:37.7

2:33.3

2:39.7

2:32.3

Not sure how to classify it.

The first 1K was on pace. The last was negative and the middle was erratic.

Kejelka just now ran almost identical, and even faster splits, minus that slow 2nd k.
