  The Swampland Distance Conjecture claims that effective theories derived from
a consistent theory of quantum gravity only have a finite range of validity.
This will imply drastic consequences for string theory model building. The
refined version of this conjecture says that this range is of the order of the
naturally built in scale, namely the Planck scale. It is investigated whether
the Refined Swampland Distance Conjecture is consistent with proper field
distances arising in the well understood moduli spaces of Calabi-Yau
compactification. Investigating in particular the non-geometric phases of
Kahler moduli spaces of dimension $h^{11}\in\{1,2,101\}$, we always found
proper field distances that are smaller than the Planck-length.
