The Best Time to Run

Yesterday evening was interval training on the treadmill. In case you were wondering, I am trying to get back in the habit of running in the evenings at least a few times per week because I want to get a little more sleep these days. I am not sure if running in the morning is better than the evening and vice-versa. Either timeframe has its pros and cons:

Morning Run	Evening Run
Pros: Much cooler temperature means I can run faster without concern of overheating. When I'm done, I feel a huge sense of accomplishment. No more runs for the rest of the day. No need for caffeine to wake me up!	Pros: More energy in the evening means my body is not stressed as much as the morning run. After taking a shower, I feel refreshed and relieved that I can sleep an extra hour. My body has more time to heal before I go to work.
Cons: It takes 20-30 minutes for me to wake up at 4:50am and get myself ready to run. In the Fall and Spring it is dark when I run which is dangerous. Running in the winter is out of the question. My body needs to heal while I am on my way to work and/or at work.	Cons: Since the evening runs are on a treadmill, my heart rate is higher and pace is slower. I have to manage my time extremely well to allow an hour in the evenings for a run. And, I can not run on Tuesday and Friday evenings due to personal commitments.
