Great advice, that would have been one of my choices. My second suggestion would be to change the background by removing people, bus, and fence, and create a grassy field with a dark wall, and then blur.Duplicate the edited version.
Convert one to a Smart Object. (Why? So we can edit the blur anytime we wish!)
Add a Smart Gaussian Blur Filter
Use the SO's layer mask and the Brush Tool to bring back the focus or subject..............In this case the lead runner.
