There is no real best time. Most people's physical peak is in the afternoon, but that is also the hottest part of the day, so in summer afternoon runs usually lead to heat exhaustion. I run at all times, depending on what time of year it is and what the weather is. During the winter, I will usually run in the afternoon, in the summer I'll run in the morning.The thing most people screw up on is running on an empty stomach. That is not a good thing. You should eat something light, perhaps a half a banana or a small bowl of cereal about a half hour before you run. Whatever it is should be easily digestible, no cheeseburgers or taco salads. Also make sure you're well hydrated. Don't jump out of bed, throw on you're running clothes and hit the road either. Give your body time to wake up and prepare for physical exertion. Do a little stretching and warm up before you run.

When you can fit it in. The earlier in the day it is the more elevated your metabolism will tend to stay and you will tend to keep burning more calories, so from a weight loss stand point the morning makes sense. Mid-day you will tend to recharge you mental batteries and get your efficiency back up, so from a work efficencey stand point in the middle of the day. Running at night allows you to unwind from the stresses of the day, some folks sleep better after exercising late other don't.So it really is up to you, when can you fit it in?

Whenever you feel like running is the best time to go. Don't push yourself to wake up real early to run because your body needs sleep. If you run on too much of a scheduled time, you will get bored with your workout and not want to do it. The most important thing is making sure you run, not the time.
