I run 5 times a week. The mileage isn't important, the number of days running is.
Five times. In the late spring, when I was still working (being overworked), my weight ballooned to 195 as my run days were cut down to two days a week because of the unrealistic demands at work (do more with less and we [a new generation of management] will advance ruthlessly on your back).
Now that I'm no longer working (yeah, I'm pointing directly at you Chris), I run five times each week. My pre-run weight has settled into the high 170s.
