  We use non-Abelian T-duality to construct new N=1 solutions of type IIA
supergravity (and their M-theory lifts) that interpolate between AdS_5
geometries. We initiate a study of the holographic interpretation of these
backgrounds as RG flows between conformal fixed points. Along the way we give
an elegant formulation of non-Abelian T-duality when acting on a wide class of
backgrounds, including those corresponding to such flows, in terms of their
SU(2) structure.
