While this does appear to be a grammatical error, Wiktionary also lists it as a dialectical, nonstandard past participle of run, so it looks like some people use it depending on where they’re from, including myself it seems.

I suppose I select ran as the past participle because in other cases where I use it in past tense, run does not sound correct to me.

For example where I am from, I would say someone “ran” from the police, instead of that someone “had run” from the police, so I default to this version of the word in these cases.
