We present our result for the strong coupling constant computed from the u-d vector Hadronic Vacuum Polarisation function. We use nf=2+1 flavours of Domain Wall fermions at 3 lattice spacings, generated by the RBC-UKQCD collaboration. We identify several possible pitfalls in this method for determining the coupling and illustrate how to resolve them.
