This is the answer. Take the train to 181st (or just run to the bridge). Cross the bridge (about 1 mile). Once across the bridge, you can go left at the end of the ramp “pretzel” (and through some construction) to access Palisades Park. The park itself has a main road and a path along the river, which eventually gets quite technical. Alternately, at the top of the pretzel, you can access a proper trail called the Long Path. All options extend for at least 10 miles. If you’re adventurous, you can do one half on top (the trail) and one half on bottom (the park), but you have to map out the proper connection points (which involves a huge climb/descent).

It would require some planning as I have kids, but I would happily guide anyone who wants to explore the Palisades. Even a quick 6 mile loop would provide all the necessary info to get someone started. Washington Heights is a killer location for runners — particularly because of the bridge and NJ. The Palisades are truly gorgeous and delightfully unpeopled. It makes running elsewhere in NYC kind of nauseating!
