Daisy Duke,
I agree with you and greyhound, I find it hard to run on a treadmill. I have been doing quite a bit of it over the winter, and find after about 30 mins I start to overheat and it becomes a real struggle to maintain any sort of pace. What always amazes me is how many people seem to exercise in the gym wrapped up in several layers! I suppose it says something about their workrate.
At the moment the weather outside on the east coast (Dundee) is great for running. Went for my long run yesterday morning with my running partner, and it was superb, cold, but no wind.
