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?

No I think you'd struggle to find someone capable of running below 10.5 in the 100 also capable of going below 29 in the 10000m on the same training. If you gave them infinite time to retrain, it is probably possible.

10.5 speed takes dedicated speed work for most runners (if they're even capable of it) and the most I'd expect a 100m specialist be able to beat the women's WR would be up to like a mile. 4:07 doesn't seem impossible for a guy running like 9.8 in the 100m to let his speed training slip a bit so he can train up for the mile.

29 on a track for a 10000m for a guy would take some heavy threshold work, but it's definitely on the weaker end compared to the 100-800 records.

Your best bet would be to get a 400m specialist and immediately have them beat the 100-800m records. Then you spend a few months and work them up into 10000m shape

Basically the question comes down to if there exists a bloke who can run 10.49 for the 100 and 29 flat for the 10k

I'm sure it's possible for an 800 specialist to train to do it, but I doubt they'd be able to execute both on the same day.

It can't be done on the same training, so set that aside.

I'd find it at least possible, although unlikely, that an individual could be capable of both, with years in between the 100m and 10000m. It would have to be a sprinter that moved up though.

at a WR level i don't think it exists. your usain bolt could run the sprints faster but couldn't do the distance end at even a competitive D3 level. i think the quickest distance runners would have more range down to about 400 but at best reach average pro women's level short sprint times, eg 11s 100m, not the WR level which takes some chops and a half second lower.

maybe you could chase it with elite decathletes with built in versatility who just haven't competed long, or if you took a special fast 10k type and said, we're training on nothing but sprints now. the latter could latently do your distance times and then could maybe be trained into college level sprint times that are the women's WRs.

Yeah i reckon a speedy world class 800m runner could do both

Someone like rudisha or korir who have/had the speed could get the 10k with a change in emphasis

Only possible for male 800m runners.

I don't have a well-reasoned opinion, but this is an interesting post!

No one can run 10.5 and sub 30:00

Broadening the question a bit, the women's WRs are roughly 90% of the men's WRs (i.e. divide the time by 0.9). Is there a woman who can get within 90% of all of the women's WRs? You might say Sifan Hassan, but I sure can't picture her running 11.6 in the 100. Athing Mu has actually run a 200 in 23.63, which is barely inside the limit. Obviously she's solid up to 1500, but could she run 11.6 and 32:15?

A guy like Brazier could have easily run 10.49 with specific training (I would bet he could have done it at his peak without specific training). Could also scare that 10k time with specific training.

Isaiah Harris won his State 200 and Mile the same year. He might be too much of a pure 800m guy though.

Hoppel? Seb Coe? Clayton Murphy?

The doped up 100 would be very tough to beat, especially since you need a good start much more than in the 200

I'd think someone like Brazier would have a shot but that's pretty much it. Or Seb Coe if he had great starting ability

This question comes up every year or so and the debate is always about the 100/200m. Personally I doubt many of the 800m guys are touching 10.5. Those last couple tenths are a lot. Feels like if they had that much speed and endurance they would be close to 44.0 low type guys and not running the 800m🤣. now the more training you allow (3 years to gain muscle and practice starts and then say a decade to develop endurance) the easier it gets. There was some Russian sprinter who ran 10.2 and a 2:18 marathon with like 10 years in between. I don’t think his 10ks was fast enough though.

And in the past the marathon was included in these discussions. Back in the 2:15 days that didn’t seem like the hardest one. These days….

We know a guy like Coe/webb basically have all the times from 400-10k but basically no 800m+ guy has a 200 or shorter post high school. we are left guessing if a 21.7 guy at 16 like overt would have been half a second faster in a couple years..

T Makhloufi.

End of debate.

Alan Webb, maybe?

Nijel Amos and Korir come to mind, we know they can both run the 400-1500 records, but the 100/200/5k/10k records are definitely in question.

No.

Webb is probably the most talented miler ever to come out of US but he’s not running a 10.5 100.
