Any elite miler (sub 3:50) should have no problem with the over distance events, and that includes a 2:15 Marathon.
They should all be capable of way under 1:53 for 800 as well. Then it starts getting tricky.
There are not many 3:50 milers who could run an open 47.6 400m. A huge chunk of athletes fall off at this distance. I'd be surprised El G could have. Aouita and Ovett at their peak could just about manage it. Interestingly Ovett ran a 47.5 and a hand timed 21.7 for 200m when he was a teen, but lost some of that speed as he became one of the world's best milers. I doubt v much he could still run these times in 1980 for instance. Anyway, the women's 200m WR is what, 21.4 now?
Some of the elite milers who are 800m orientated should make the 400 time.
Once we get down to 200m then there are only a handful left. Cram couldn't run a 21 sec 200, nor Aouita or Webb. It leaves us with the likes of Ovett, Coe and Rudisha. However the latter is a 400/800 specialist, and I doubt he could break the women's marathon time. Possibly the 10k. While he'd have no problems running a 21 sec 200, I think he's just too tall and gangly to be able to explode out of the blocks and run a 10.61 100m, let alone 10.49.
I don't think people realise just how fast 10.49 is, and how much specialised training is required.
With specialised training for a season or so, Coe and Ovett might get down to 10.6, but even they would be unlikely to run 10.49.
I think the best overall bet would have been Coe in 81. He was certainly capable of the over distance times for women's WR's as they were then and probably as they are now.
He ran a 45 sec relay leg and is credited with 21.7 for 200 at the end of a set of reps. In a one off race fresh, then that should come down a few tenths. I think he'd have been very close to the then women's 100 WR of 10.88 as well, though 10.49, the current WR, would probably elude him.
