Do you run regularly? For how much time?

Pay attention to what your body tells you, that will be the guide to whether you are a morning runner, or do better at another time. Of course, you also have to work around the commitments of your day.

Whether or not to snack depends on whether you are running to lose weight or build endurance. If wanting to lose weight, then run with an empty stomach. This will force your body to burn your body fat to give you the energy you need to sustain your running. If you're building endurance then eat healthily but not heavily.

I do brisk walks. A lot. Many times thruout the day. Climb updown the stairs.
Stopped since a couple of days. Will resume.

I prefer randomly at any given hour.
Pathway ought to be clear. Doesn't affect my system, if I walk after snack. Eating while walking used to be the case.
No more now.

never heard of people running with a snack... only really got time for it on the weekends and not more then 5 miles
