I prefer running when it's cold. Is it because I started running in January? Is it because I grew accustomed to the cool weather during those first few months (an instrumental time when you’re trying to decide if a new practice is something you want to continue for the long term)?

(For the sake of clarity, let me be more specific when I say that I prefer running in the cold: I’m not talking about sub-zero temperatures. I’m referring to the concept of cold in northern Virginia. Also keep in mind that it hardly ever snows here during the winter.)
