I am thinking about getting one of those polypropylene tops to wear under my t-shirt when running. It will be good for running during winter. It is a good material for absorbing sweat away from the body, and it should keep me warm.
I borrowed one of Dad's on Monday. It was a short run, but I noticed the difference. His one has short sleeves, though. One with longer sleeves would be better.
I entered the BMW half last Friday. It is not until November (during exams), so there is plenty of time left to train. I am going to ask Dad about his long training runs (from his training records) and start doing some of them. Some of them are really long - which will be excellent for building up stamina.
