Well he's definitely a marathon runner and your capture of him is quite fine. I am bothered by the police line tape running accross the background and the background might have been blurred for less distraction.
This is a very nice, clear photo. It seems a bit out of place to me that on the front of a runner's magazine that you can't see any of the legs of the runner. I think I would like it better pulled away a bit to see the legs.
Nice shot, well taken. The motion blur of the left hand makes me really appreciate the sharp focus of his face and torso. Great expression of concentration captured. It's a shame the background doesn't work so well. No shapes there help with your composition, and it looks a bit mundane. The dof works well though.
Certainly room for the title at the top. There is a little blurring of the hand, but it suggests motion, the rest is nicely sharp, and well exposed. I could see this on the cover of the magazine.
