Abstract: The evolution of the strong coupling constant $\alpha s$ from $M Z$ to theGUT scale is presented, involving three-loop running and two-loop decoupling.Accordingly, the two-loop transition from the $\bar{ m MS}$ to the $\bar{ mDR}$ scheme is properly taken into account. We find that the three-loop effectsare comparable to the experimental uncertainty for $\alpha s$.
