I agree with these suggestions especially when it comes to what you are wearing with particular care given to layering. Perhaps you could start slow once the weather gets cold and test out your clothing and health - running a only a mile (which would have you in and out fairly quickly) for a week or two and see how that goes. If that works up your mileage to two miles and so forth. Good luck as there's nothing better than being outside rather than a treadmill (in my opinion).
