I live in Toronto, Canada and its still very chilly here about -3 celsius (26 degrees farenheit) on the average, I noticed that I dont really sweat alot because its so cold right my question is, are there any advantages to running in that weather, I know there are plenty of disadvantages like catching a cold, or pneumonia or when its colder, frostbite!...but are there any distinct advantages to running in cold weather?
