We discuss the running couplings in the standard model, SU(3)CβΓSU(2)LβΓU(1)Yβ, when the Higgs sector is replaced by SU(NTCβ)
technicolor. Particular attention is given to the running of the couplings at
momentum scales where technicolor is nonperturbative, and in this region we
apply a relativistic constituent technifermion model. This model has been
tested against the known running of the QED coupling due to nonperturbative
QCD. An understanding of this low momentum running allows the calculation of
the couplings at a higher scale, Ξpertβ, where technicolor becomes
perturbative. We provide numerical values for the changes in the three standard
model couplings between mZβ and Ξpertβ due to technicolor, assuming
separately ``one doublet'' and ``one family'' technicolor models. The
distinction between a running and walking technicolor coupling is also
considered.Comment: 14 pages of LaTeX, UTPT-94-
