We simulate SU(2) gauge theory with six massless fundamental Dirac fermions. By using the Schrodinger Functional method we measure the running of the coupling and the fermion mass over a wide range of length scales. We observe very slow running of the coupling and construct an estimator for the fermion mass anomalous dimension giving 0.135 < γ < 1.03 in the region compatible with an IR fixed point.
