  We use a simple model to extend network models for activated dynamics to a
continuous landscape with a well-defined notion of distance and a direct
connection to many-body systems. The model consists of a tracer in a
high-dimensional funnel landscape with no disorder. We find a non-equilibrium
low-temperature phase with aging dynamics, that is effectively equivalent to
that of models with built-in disorder, such as Trap Model, Step Model and REM.
