There's an argument that stress is bad, because it forces the body to prioritise immediate survival at the expense of long term health.

However, simulating a hunt should be good for the health since it informs the body that it is in a prey rich environment. The same goes for other stressful but evolutionary fitness promoting activities such as sex.

Any stress-related problems from running (not a point I'm conceding as I've never seen evidence of any) certainly outweighs the long-term problems from being overweight and out of shape with the lower respiratory capacity to boot.
