We investigate the dynamic relaxation of random walks on temporal networks by\nfocusing in the recently proposed activity driven model [Perra \et al.\nSci. Rep. srep00469 (2012)]. For realistic activity distributions with a\npower-law form, we observe the presence of a very slow relaxation dynamics\ncompatible with aging effects. A theoretical description of this processes in\nachieved by means of a mapping to Bouchaud's trap model. The mapping highlights\nthe profound difference in the dynamics of the random walks according to the\nvalue of the exponent \γ in the activity distribution.\n
