I once got a really good sound of a horse or other large animal running on dirt or gravel. I did it by beating two potatoes in a 3-beat rhythm in a pan filled with sand, rice, and crushed crackers. Pitch adjusted to suit.

For horse hooves, cup your hands and clap them against your thighs to the running horse rhythm. Works best when you’re wearing denim pants.
