I'm 43, I walk 95% of the rounds I play on my course. I'll ride for scrambles and some courses I travel to play (depending). I have a pushcart and used it predominately over carrying because it saves my legs, but more importantly my back, until recently I purchased a 2.2 lb Titleist golf bag.
I like the fact I can run with my pushcart. I know that might sound foreign with golf, but I have drop foot and Parkinson's, and if my medicine isn't kickin' in right then my right legs drags, which causes me to drag behind on the pace I want to keep. So, for me, running can be so much easier at times when the meds aren't in full effect than when walking.
However, I have walked a majority the past 4-6 months with the lightweight bag because it it allows me to walk across the green and set my bag toward the next tee box, rather than walking around the greens. Also, its been more efficient than my push cart due to the rain and some marked off areas.
When summer comes around I'll probably be back to the push cart, but regardless I don't care what others say about using a pushcart. I use it and they've got to deal. I would say, since I've been walking, many of the other 10 guys in the group I typically play with are usually walking now as well.
