The topic of whether it is disrespectful to run in a cemetery comes up regularly on the running subreddits, and is always a divisive subject.
My usual contribution to those threads is to suggest that people go to the cemetery’s web site and look for their “rules and regulations”, or call the cemetery office and ask. (Cemeteries are typically just small businesses.)
I think the best question to ask if you strongly want to run there is, “Does the cemetery have a policy against running/jogging on the grounds?” I think that is more likely to get the response you want than “Is it OK to run here?”
One of the largest cemeteries in my area has an explicit policy against it. (I did illicitly jog there early one morning. See a brief anecdote about that in this post.)
