Start running at 25 yo, is it too late to achieve at least 80% of your potential (5k+) ?

You can get very near your potential if you continue training into your late 30s. No one gets their theoretical best time anyhow unless they move to altitude, don't work a full time job, etc. Just go for it and see what you can do.

So you suggest e.g Brendan Foster, Ron Hill and many,many more with fulltime jobs and no altitude training didn`t reach their potential ? What you say is of course not true.........

I think not getting close to your genetic potential when starting in your mid twenties has more to do with life getting in the way than the person being too old.

It's generally easier to train hard when you're a teen with few responsibilities than when you have bills to pay and a job to take care of.

Then why do people here talk about how they get injured more easily in their 20s compared to their teens?

I said the main reason, not the only reason.
