Rudisha time predictions for 100m through marathon

You cannot break 46 without sub 11 second speed. The basic conversion for the 400m assuming you have the perfect endurance is your best 200m x 2 + 3.5 [ however this can get down to 3.0 when you approach 43-45 seconds due to the fact that you spend lest time under heavy lactate.

So Rudisha for instance running 45.5 [Pre-comp, Not even in season] is between 21.00-21.25 for 200m. Further this means that he is under 11.00 for 100m.

In any case here is a link to a conversion chart by Frank Dick who was the Director off Coaching in Great Britain.

And if your too lazy to view the chart here is an online calculator which the same data.

FYI Rudisha running a 21.25 = 10.57-10.64 electronic.

21.00 = 10.49-10.56 & that is only pre-season.

So as much as it may kill some people when he is in 44.5 shape [800m 1:41.01] he is likely 20.75 which is 10.33-10.40

I hope you are trolling.... There are hundreds of JV kids in highschool that run sub 12 every year and you are saying that he can barely do that? Again I hope that you are trolling.

These middle school boys and girls comparisons are dumb. Just because a middle schooler can run 11.xx for 100m, does that mean that an adult like Jordan Hasay should be able to?

I would hope that a middle school 100m specialist would be able to beat a mid distance runner at 100m. Just like a middle schooler/jv would beat Usain Bolt in a mile or a 5k.

It depends on the middle schooler. Usain Bolt would beat most if not all middle schoolers in the mile. 5k is a different issue but keep in mind how removed the events are. 800 to 100 is separated by 2 events for Rudisha and for Bolt 200 and 1600 are also separated by 2 events so it is a somewhat fair comparison.

On a separate note anyone who predicted over 3:34 for the 1500 is not too bright. How can you honestly think that Robby Andrews is better than David Rudisha?!

I'm loving all the furor, keep it coming.

Just to exacerbate things, I'll point out that we're talking about 100m FAT, from the blocks.

To exacerbate things further, I'll add this: what do you guys think Rudisha's 60m time would be, FAT, from the blocks?

It's not a debate its a fact. I cant really see your logic. 11.5 out of blocks in a 100m is slow. I'm sorry if that hurts your feelings. I ran x-country, did no speed training and still ran 11.6 out of blocks FAT as a 16yr old.

Your name says Sprintgeezer yet you seem to know nothing about the sprints. Rudisha has run 45.5 FAT out of blocks. It's physically impossible to run that time without breaking 11.00 FAT out of blocks.

But you must obviously have some secret that John Smith or Dan Pfaff or any other elite coach doesn't know. Please enlighten the masses on how to somehow run at your max velocity for 400m.

Your so thick.

According to the charts he's 6.78 when he's at 21.00 shape for 200m. His speed endurance would be higher than that of sprinters though and his acceleration alittle less to 6.90

I actually saw Seb Coe run 11.01 FAT out of blocks in a meet in Loughborough University at the beginning of his competition season. He is an 800m/1500m runner and has only run mid 46sec for 400m. You can guarantee Rudisha breaks 11.00 easily.

Talking of past runners, There is actually footage of Colin Jackson talking to Wilson Kipketer and the topic of his actual 100m speed came up and he said during summer he runs some 100m reps with electronic timing to see where is speed is at and he ran 10.70's for both.

I think some people forget the 800m is essentially an extended sprint. Pretty much you wont be able to make the 800m A standard without a minimum of 11.40 FAT speed, and even then your endurance will have to be maxed out just to run 1:45.6 because your 400m time off that sort of speed will only be around 48.00 out of the blocks.

100m 10.8

200m 20.1

400m 44.5

800m 1:40.9

1500m 3:32

5000m 13:35

10000m 28:30

Marathon 2:30:30

OP didn't ask for a 60m time and no one cares.

Didn't Galen Rupp record some 10.9s?

It was a flying start.

here is the thread:

Kipketer, 10.70 for 100m...flying, not from blocks.

THINK about it: why would an 800m guy want to see where he was at in the 100m from blocks? WHY would he want to assess his block start performance when it is irrelevant to his event?

You guys are REALLY thick.

BTW, 10.70 for Kipketer in a flying 100 is totally believable, as it is for Rudisha.

And, the 800m is NOT an "extended sprint", even for men. We have been through this before. Although there is a significant anaerobic component, it is NOT a "sprint". A "sprint" incorporates start and drive phases, and different form from an 800m run.

You don't think anybody could run a 45-400 with an over-11 100? Think again. Kipketer could go 10.70, Rudisha can do the same. It is not a true sprint, therefore they can do more than one of those in a row. Let's be generous and say 10.8 for a flying 100, that is 32.4 for 300m, leaving 12.6 for the first 100 from the blocks. Add .2 to each of the last 3 100's, and you have an initial 12 from the blocks.

You guys are absolutely hilarious.

Sprintgeezer

If Kipketer could run 10.7 w/ a flying start, maxxed, there's no way in the world he could run 32.4 for 300m. Even MJ, who trained specifically for the 200-400m, and was an all-time great athlete at those 2 distances ran his 3rd 100m significantly slower than his previous 2. His time for 200m of 19.32 dropped to 30.85 over 300m, a full 1.5 secs slower over that 3rd 100m.

Further, you're assuming 12secs for the first 100m, which means he'd have to go 10.8 for the remaining 3x100m - maxxed out, for the backend 300 of a 400m, after running a maxxed out first 100m. That's nonsense.

And of course Kip would want to see his 100m from blocks - there's no better objective measurement of speed than from a definitive start. Increase the # of variables, as you do with flying starts, and it becomes impossible to measure accurately.

The idea that a 45sec 400m, i.e., a world class 400m runner, can't go under 11 from blocks, is nonsense.

He has absolutely no answer to any legitimate posts. 45.5 is 11.37x4. I cant for the life of me understand the stupidity. The 400m with perfect endurance is your best 200x2 + 3.5 so 200m is 21.00 and thats not even during his peak!

Coe has run 11flat Fat from blocks. Marcin Lewandowski ran 10.61 Fat as an 800m runner confirmed by iaaf. Lachlan Renshaw has run 11.06 and 47.0 fat one week out from running 1:47. Rudisha has run 45.5, which is impossible with 10.xx speed. Highschool 800m runners across the country run 11.5 fat. The fact is you must break 11 to run under 1:43. Shit I ran 11.49Fat out of blocks in little athletics as a 14 year olf and I was a 4/8 runner. 11.5 is slow for a girl, and basically a sign of no speed for a guy. If your running 11.5fat out of blocks your coach will tell you that youll never cut it in the 800. And it is a sprint when you require 46low to 44high speed to medal. Times fast enough to make most olympic 4x4 teams.

Rudisha runs 44.xx at his peak enough to medal in the olympic 400m. The 400 is a sprint right? Surely your trolling, you cant be that dumb

Why are you guys arguing with Sprintgeezer? Making ridiculous claims about the sprinting abilities of distance runners is his thing. It is his raison d'etre, don't take that from him.

I ran in the world juniors in beijing 06. Rudisha was a year younger than me and won in 1:47. I only made the semis. I clocked 11.19 fat prior to departure on the gold coast. Marcin lewandowski made the final and he clocked 10.61 fat into a negative .4 wind a month after world juniors. My team mate ran 11.03 fat out of blocks prior to departure and he ran 1:47.00 in the heats. These are junior times. Rudisha now run 1:41.01 so he is obviously well under 11.00. 800m isnt a distance race.

Yes, I haven't seen that time before, but I wouldn't doubt it. He used to run the odd 100, 200 & 400 for Loughborough uni in pre-season meets, usually held in April and May. So you can probably knock a tenth or 2 off by the peak of a season (August) when he'd have done a lot more speed training.

If you saw it actually at Loughborough, then it would probably have been on cinders, as it wasn't turned into a synthetic track until 1983, after he'd left to run for Haringey. That would also make it worth a tenth or two faster.

I've also read in an AW interview at the end of 85, that he had been loosely timed at 10.6 during reps in training, so probably off a rolling start.

He also ran 21.5 in training for 200m.

If you look at this 400 relay leg in 45.7

he was practically hobbling through the start and yet he hit 100m in c. 11.2,

200m in 22.1, 300m in 33.4 and finished with a 12.3 easing up.

So I'd say that from the blocks in peak form Coe would have been capable of something like 10.8, 21.4, 45.5. Now, despite impressive basic speed for a middle distance man, he was more of an 800/1500 type.

Rudisha is clearly a 400/800 type, so his best from the blocks must be slightly faster than Coe's. However, Rudisha is a much bigger guy than Coe, so I doubt there would be much difference in a 100m from blocks. It would take Rudisha a bit longer to get into his running. And I don't think Rudisha would be capable of running 200m faster than Juantorena (a 44.26 400m runner) who has a listed 200 pb (from Mel Watman's Encyclopedia of T&F Athletics) of 20.7.

Rudisha's 200 best from blocks would be somewhere between Juantorena's & Coe's, so that brings us to around 21.0/21.1.

I'd say a peak Rudisha would be capable of 10.8, 21.1, 45.0 from blocks.

And there is no way he's going to be capable of 3:30 for 1500. Certainly not off his current 800 training. Perhaps, like Cruz he could run 3:33/3:34.
