  We generalize the action for point particle motion to a double field theory
background. After deriving the general equations of motion for these particle
geodesics, we specialize to the case of a cosmological background with
vanishing antisymmetric tensor field and constant dilaton. We then show that
the geodesics can be extended to infinity in both time directions once we
define the appropriate physical clock. Following this prescription, we also
show the existence of a singularity-free cosmological solution.
