I think it is time to give that hamstring a week or two off. No direct work just let it be support in other leg movements. Of course run that by Pat but he normally tells me to use my best judgement, and adjust as needed. As we know he is a coach, not a physical therapist. See if you can find a bike or something instead of a treadmill if that is what you have been using walking on an incline is going to beat it up a little too, so might as well look into a bike or elliptical to get a little less hammy stimulation.
