I've been working on a transformation as well. In 2 months I went from 192 to 173 lbs. My goal is to get a single digit body fat % (somewhere between 6% and 9%) and thus get more muscle definition.
I haven't been running though. I've been doing HIIT or interval training on my stationary bike three times a week, I've been lifting weights three times a week, and I've been dieting. I'm not where I want to be yet, though.
I need to up my protein intake to preserve and -- god willing -- gain muscle, and I need to keep my intensity up in the gym. Hopefully I'll be able to get as lean as I'd like in a month or two.
