Dr. Renato Canova talks about Ruth Chepng’etich’s world record.

So then EPO doesn’t work on Kenyans?

"Dr. Renato Canova"

lol

So are you saying that a 30 year old woman distance runner can't have a natural VO2max of 70mll/kg/min?

I don't understand why you seem so adamant about trying to convince these rabid, jealous envious, mediocre weekend-joggers on this site about anything. Their minds are firmly made up and no amount of what you say will change them.Unless of course you are speaking about their poster child for what can be achieved with unchecked medical assistance, the norwegian lab experiment.

200 Kenyan suspensions and counting.

what's really interesting to think about is if Kelvin Kiptum had been part of the original Breaking2 marketing event, he would have actually accomplished it in the original vaporfly, and then we might never have the alphafly because there would be no need for it to be developed

Ruth clearly couldn't have done this in just the vaporfly

Chicago was basically the women's Breaking2 event, not quite the same levels of draft but good enough

Yeah, ignore the knowledgeable coach.

Indeed. People overlook the massive benefit of having tightly packed pacers the entire way. Kiptum's WR involved, if I remember, running with pacers for a whopping 5 km.

and go watch Tigist Assefa at Berlin 2023 with the 2:11

I think the only time she wasn't behind her pacer was the final 100 meters after the arch

the benefit is HUGE, not as small as people think

wasn't Radcliffe 2:15 behind a pacer the whole way until that final turn at the end of london?

imagine Radcliffe with alphaflys so +3 vdot, she'd run 2:11 or 2:10 too

I second that sentiment too.You are wasting your time trying to have an objective discussion on this topic with this lot.Any other subject then maybe you might get some objectivity.

FYI: Based on the standard formulas, an estimated VO2 max for a female running a marathon in 2:09:57 is around 83-84 mL/kg/min

There is movie about this

Here is a really great reminder about Eliud Kipchoge's performances

1. before super-shoes at all (2:04 like clockwork, much younger too)

2. then with the Vaporfly with a draft (Breaking2 2:00:25)

3. then Vaporfly without a draft (2:03)

4. then Alphafly with a draft (1:59:40)

5. missing Berlin 2022 Alphafly without a draft 2:01:09 (did Rolows ever add it before he seemed to retire?)

The differences are striking and dramatic and obviously proportional when scaled to 2:15 women becoming 2:10 from vaporfly to alphafly with a draft

You didn't answer my obvious question.

Why not?

But VDOT isn't VO2max is it?

New shoes are especially advantageous for women? If that's not just made up, can someone please post a link to that research? I hadn't heard that.

it getting hard to watch this clown show parade of marathons, with carbon plated spring loaded shoes, and Athletes using EPO, Steroids and who knows what else. To run a 2:09 you would have to be 13:30 5000M runner or a 28:15 or so 10000M runner...i dont recall any woman running these times.
