Running downhill is harder on the knees, my P.T. sister very much agrees. If your knees are complaining at all, slow down or walk, is my suggestion. Well, that's working for me, but you're not me. FWIW.Pretty reasonable to take caution, would be unfortunate to cause an injury. I do some downhill trail running to get my heart rate back up, since walking downhill often leaves my heart rate in the 110-120BPM range. Kinda depends on my training plan for the day.
