STEP 1

First, as always, duplicate your Background Layer before you start. To fake the blur, you’ll need to select the subject, move her to her own separate layer, then blur the background. If you blur the background without first cloning out the cyclist, you’ll see a blurry cyclist behind a sharp one. So before you add the motion effect, remove her. Duplicating the Background Layer ensures that you always have your original to go back to, even if you mess up.
