thought about pacing 800 vs 5k WR

Different energy systems, they don't scale in a proportional function.

3k @ 5k world record pace is 7:33: 1220 IAAF points (60% of the race)

600 @ 800 world record pace is 1:15.68 1123 IAAF points (75% of the race).

400 @ 800 world record pace is 50.45 848 IAAF points (50% of the race).

makes sense to me. thanks!

this is not right. To pace the 800m WR the rabbit would have to go around 49 flat for the 400m and 1:15 flat or under for the 600m.

It's average pacing, not what actually occurs on the track.

pacing to 600 for a 800WR woud be easier, mainly because 800WR number itself isn't great at 1'40.91, the number not the talent who ran it & also lotta elite guys woud seriously improve their 800pbs if they ran a more sensible race

the pacing for 5k is tougher

wr is 12'37.35 needing splits of 7'34.41 & 10'05.88

the way to think of it is what 5k ability do you need to be able to pace a 5k thru the above ?

the pacer has to be a top elite themselves & lets say they have 3'32/3'33 speed for 1500

to pace thru 3k in above split, the 5k ability ->

3'32.0 / 3'33.0 / 7'34.41 ->13'12.3 - 13'14.7

plenty of elite guys coud do the pacing to 3k, needing above 5k ability, but they woud have to drop out at 3k as finished by then

if you want the same pacer to keep going to 4k, you seriously need to jack up their 5k ability

3'32.0 / 3'33.0 / 10'05.88->12'48.2 !! - 12'48.2 !!

bottom line, if you want the same guy to pace to 4k at wr pace, he needs to have current

~ 12'48

ability

clueless

do you think guys who can run 4k in 10'05 grow on trees ?!

what kind of 5k ability do you think it needs to run 10'05 ??

CRAZY 4:00 mile pace!! 60 per lap for 10 laps!!!

no

I'm pretty sure Bekele and Komen went through 3k in 7:37 in their WRs while Geb was 7:40. It is quite possible that running behind the pacemaker conserving energy doesn't require exactly 7:33 but again there isn't that many on the scene at the moment capable of running such a time.
