was caught, had run

[Tukanja]

Would someone please tell me is this sentence grammatically correct?

He was caught before he had run half a mile.

[ETutor]

Yes, this sentence is correct.

[Tukanja]

was caught ~ the Simple Past Tense ( Passive Voice)
had run ~ the Past Perfect Tense

deep past~~~~~~simple past~~~~~~~present perfect~~~~~~present~~~~~~future

the Simple Past before the Past Perfect
How's that possible
?

Explain this for me please

P.S. I might accept the sentence

He was caught before he had been running half a mile.

but not He was caught before he had run half a mile.


Also why not

He was caught before he ran half a mile.

[Tukanja]

I think I've understood why the sentence is a correct one.

Between all the other usages, the Pluperfect Tense is also used for expressing somebody's or possible or even imaginary intention before the second action happened by way of interrupting or disabling the intention.

I picked up the flower before some other had done it.

Right?

[Tukanja]

Let me try now say this in a bit different way

Seems to me that between all other its usages, the Pluperfect Tense is also used in phrases for expressing either possible or even imaginary intention that could happen before the second action happened at time of speaking and by way of interrupting or disabling the intention.

I picked up the flower before some other had done it.
I got out before the bomb had exploded.
