Do you think there us a single man that could run faster than the women's world record in every track event 100-10,000?

10.6 hand-timed is 10.8 electronic. A long way from 10.5.

+1. Webb was a monster.

Yifter couldn't have run 22-flat for the 200. If he did he would have been an 800/1500 runner, like Snell.

There is absolutely no way Borzakovsky ran 10.3 for the 100m.

It's in the WA article. I am sure they know more than you do.

I very much doubt Rudisha could run 10.5 or better for the hundred. If he could he would have been able to beat 21 for the 200. That would put him in Juantorena territory, who ran 20.7 and 44-low. Rudisha couldn't do that or he would have competed regularly over one lap. He didn't.

He didn't run 10.3 from a standing start. It was a flying start - which translates to 11-flat at the absolute fastest but probably closer to 11.2, since a top sprinter will gain nearly a second off a flying start over that distance. (Armin Hary 10-flat ht runner and 9.2 in a relay; Bob Hayes 10-flat FAT and 8.9 in a relay, Usain Bolt 9.58 and 8.6 in a relay).

So Borzakovsky wasn't any faster over a sprint distance than Coe, Ovett or Snell.

Actually, there was an experiment when a natural 400/800 pro runner tried really hard to compete at 3K/5K - so you can draw projections.

I am talking about Caster Semenya LOL

Sure, 400 times are coming up a lot for two big reasons:

-A man would have to be capable of a long ways below the women’s 400m WR in order to be capable of both 10.49 and 29:01.

-Most all of the guys we believe could beat the women’s 800 through 10k WRs have never recorded a FAT 100 or 200 time, so the best we can do is extrapolate down from their 400 times.

…

Count me among those who don’t think anyone could have done this. If you’re thinking about someone being capable of all simultaneously, I think that’s absurd. If we’re talking at different points over a number of years it’s of course more feasible, but I think we’re probably about maxing out at a handful of 10.7s + 28:50s guys. Wilson Kipketer, Seb Coe, Joaquim Cruz, Abubaker Kaki, Taoufik Makhloufi, Yuriy Borzakovskiy, and Donovan Brazier would be among the candidates to be 10.7s + 28:50s guys, but that’s not to say I think they’d all get there. Note that the slowest 800 PB among that group is 1:42.61.

Guys like Cram and Snell could probably never have had the explosive acceleration to even break 11.00 FAT. There’s a huge difference between turning on the afterburners with 200 to go in a mid-d race where you’re the strongest aerobically, and getting out well in the first 50 of a 100m dash. Snell himself said he thought he was the slowest sprinter in one of his 800m Olympic finals, crediting his success to his aerobic development from running 100+ mile weeks. On the other end, I think Juantorena, Rudisha, and Korir could have broken 21.00 if they’d strived to, but as 400/800 guys that does not mean they could have run 10.5, and I’m practically certain they could have never run 29:00 either.

- She took 113.22% of Rudisha's time to run her 800m PB

- if we assume that Rudisha would have run 1.5K, 5K with the same scalar (1.1322 times faster than her) - we're getting him running 3:31.9 1500 and 13:43 5K. This speed is more than sufficient to beat 10K women's record as well.

Here is my argument is one post:

1. Both Caster Semenya and Rudisha were naturally 400/800 athletes.

2. There's no doubt that Rudisha could have broken 10.5 with his 45.5 speed and some training on his start.

3. Caster Semenya has her 800 pb 1.1322 times slower than Rudisha's

4. She trained really hard to compete at 1.5K, 3K and 5K

5. If we hypothetically assume Rudisha's 1.5K and 5K 1.1322 faster than Semenya's, we're getting to 3:31.9 1500m and 13:43 5000m. Clearly, 13:43 person can beat women's 10K record as well.

Case closed?

Snell would have been closer to 11-flat than you might think. He could run just over 22 for the 200 (faster than Cram). I would guess his 100 limit would be 11.2. Nowhere near the fastest 800 guys - or the women's wr. He would be borderline at the women's 400 record.

Juantorena had a best of 20.7 for the 200, which is truly exceptional for an 800 runner. I don't think Rudisha could run 21-flat or he would have been a top 400 runner, as Juantorena was. Korir, maybe - as he has run 44-mid.

Rudisha wouldn't have broken 10.5 or he could have run below 21 for the 200 and so been a 44-guy for the 400. He wasn't - or he would have competed over that distance. There is also no way Rudisha would have run 13:43 for the 5k - it is out of range for an 800 specialist. Case not closed.

Rudisha might be the purest 800 runner in human history, there's no way he would've been a 3:31 guy.

The women's 800 is a slightly more aerobic event than the men's 800, so it stands to reason that Semenya's conversion times at distance would be faster than a speed-based 800 male trying to do the same

Kratochvilova disagrees that the women's 800 is more aerobically-based.

She was as fast as Snell over the 400 - and faster over 200. But 9 secs slower over the 800.

Actually, I think we’re on the same page regarding Snell.

Rudisha ran 45.50 FAT in February, and 45.2 hand-timed in Nairobi, on limited attempts. I don’t think 44.9 is out of the question, and 45.low seems like a safe bet. That puts 20.99 in play, especially if he paid it some attention and worked on his start—he’s still not running 10.49 or faster though. Korir’s done a little better than your 44-mid with a 44.21, actually faster than Juantorena’s best. Granted, that was at altitude in Nairobi, but he also ran 44.37 in Doha to qualify for the World Championship final. That should make sub-21 almost a done deal.

Korir ran XC for UTEP in 2016. His 10ks were 33:35 at regionals and 33:33 at nationals for—get this—249th out of 251 finishers.

The women’s 800 is slightly more aerobic because it’s a ~1:55 race as opposed to a ~1:42 race. It’s pretty clear cut.

Using Semenya’s times as proof that Rudisha was capable of such-and-such doesn’t hold any water for me. There are obviously plenty of 49.6/1:54.3 guys who couldn’t run as well as Semenya at the longer distances.

Did those 49.6/1:54.3 guys REALLY try to spend a few years and put 100% effort to become the most competitive at 5K? How do we know their true potential at longer distances?
