  We study SU(2) gauge theory with two fermion flavors in the adjoint
representation. Using a clover improved HEX smeared action and the gradient
flow running coupling allows us to simulate with larger lattice size than
before. We find an infrared fixed point after a continuum extrapolation in the
range $4.5 \lesssim g^{*2} \lesssim 5$. We also measure the mass anomalous
dimension and find the value $ 0.25 \lesssim \gamma^* \lesssim 0.28 $ at the
fixed point.
