Could Kipchoge run a sub 4 min mile right now with specific training ?

no

With 10 weeks of training, it's possible but highly unlikely. On the day of Berlin, no shot.

Absolutely yes he could its not even hard to do anyways.

You think a guy who can run 26 straight 4:38 miles cant break 4? Of course he can all he needs are some warmup strides and he'd be 3:59 easy.

lol, yes

Are those who are saying "no" trolling? Cause that's some funny sh*t!

Of course, watch out for him in heat #2 of the mile at BU this winter

Yes. During this past Berlin marathon he ran a 2:36 (4:11 mile pace) split during for the 22nd km. And then an other 2:37 (4:13 mile pace) for the 39th km.

He would not even need 10 weeks of specific training.

the better question is what is the shortest distance kipchoge could beat athing mu in?

I highly doubt that those splits were accurate given that his fastest 5k split was 14:09 (a 250/k average).

However I do think he could break 4 with pretty minimal specific training

It's an interesting question. My guess is yes... But, I could be wrong. It's easy to assume he could just crank out a mile at 35-40 seconds faster but he's highly trained to a specific pace range and there's probably not much gap between his max 5k effort and his marathon. That's my guess. I think he could do it, but maybe not.

This is where I found the splits :

The key to Kipchoge's success is that he sticks to his routine and doesn't chase gimmicky goals that would get him injured and do nothing for his legacy.

The difference between 2:37 and 3:12 in consecutive km's at 39/40k suggests that the kilometer mark between them was in the wrong place, the first too short, the second too slow.

Same with the 22nd kilometer, listed as 2:36. The k's around there are about 2:50-52. It is listed as 16s from the 21st kilometer to the half. If you add that 16s to 2:36 (22nd k), you get 2:52, which is right on par with the other k's around that.

Of course Kipchoge could still run sub-4:00 for a mile, if he trained for it. It’s not even a question. But why would he bother?

He wouldn’t, unless he thought he could go sub-3:43, which he knows isn’t going to happen.

Yeah, those kilometer splits from Berlin are not accurate. Next you’ll be telling me Yehualaw split a 4:43 mile.

I think he could do it, but he wouldn’t blow it away. I’m thinking 3:57-59 range, so maybe it’s not such a bad question.

He could roll out of bed tomorrow and do it, not even a valid question.

idk Nick Willis has trained for the mile specifically for the past 20 years and this year it took him a few tries to just barely dip under. And that was with him running 3:35 just 5 months prior. Kipchoge's endurance is undoubtedly otherworldly, but when was the last time he even touched something close to 4:00 pace? He's been in full on marathon training for a decade now, and I'd be surprised if he's done anything more than strides at 4:00 pace in that time.

How many people have run sub-4 past the age of 35 after completing a marathon? Any? Kipchoge is certainly a different beast, but if Nick Willis (rightful 2008 Olympic Champ peace be upon him) is struggling to do it a few months after a 3:35, it makes me a bit skeptical that Kipchoge could just drop down and after 10 weeks of training knock it out.
