We study the relaxation of a class of functionals defined on distances induced by isotropic Riemannian metrics on an open subset of RN\mathbb{R}^N. We prove that isotropic Riemannian metrics are dense in Finsler ones and we show that the relaxed functionals admit a specific integral representation.
