  We consider a closed three-dimensional contact sub-Riemannian manifold. The
objective of this note is to provide a precise description of the
sub-Riemannian geodesics with large initial momenta: we prove that they "spiral
around the Reeb orbits", not only in the phase space but also in the
configuration space. Our analysis is based on a normal form along any Reeb
orbit due to Melrose.
