Abstract
In this paper some subdifferentials of distance function from a closed subset in points outside of the target set are introduced in the context of Riemannian manifolds. The subdifferential regularities of distance function \(d_{S}\) and normal regularities of enlargements of a set S are also studied in this setting.
