So I've been running now for a few years and have stuck to compression shorts/running tights (under a pair of shorts - no budgie smuggling allowed!!) and then just a running tshirt (long/short sleeved technical top)..........
I've always looked at running in trackies or with a jacket/windbreaker as an extra weight/inconvenience but more and more people I see now in the winter are wearing them....
Whats the pros/cons for running with added layers of this kind?
