We determine the complete NLL running of the static potential associated with the locally 1/2 BPS Wilson loop in N = 4 supersymmetric Yang-Mills theory. We present results for the SU(N-c) singlet as well as for the adjoint configuration and arbitrary Ne at weak coupling. In order to derive the respective anomalous dimensions we perform a two-loop calculation in the N = 4 supersymmetric version of the effective field theory pNRQCD. In addition we confirm the recently obtained fixed-order result for the singlet static potential generated exclusively by ladder diagrams to the third order in the t%26apos;Hooft coupling. We also give an explicit expression for the logarithmic contribution of all non-ladder diagrams at this order.
