  We present the analysis of the static potential extracted from Wilson loops
measured on CLS ensembles generated with Wilson gauge action and Nf=2 flavors
of O(a) improved Wilson quarks at three different lattice spacings and a range
of quark masses. The shape of the static potential at distances well below the
string breaking region is studied in terms of renormalized couplings derived
from the static force and its derivative. We comment on the (im)possibility of
extracting the Lambda parameter at our smallest lattice spacing a=0.05 fm.
Finally we give an update on the scale determination through r0.
