  At present and future hadron colliders, the precision physics program started
in the past will be continued. In particular, a precise determination of the W
boson mass will be carried out. This requires the calculation of the radiative
corrections and their implementation in Monte Carlo event generators for data
analysis. In this talk, the status of the calculation of the order alpha
electroweak radiative corrections is reviewed and a study of the impact of
higher order QED corrections on the W boson mass is presented.
