Back when I was running 8-12 miles regularly, I would run two loops of 4-6 miles, with one stop at the house. Before starting the run, I would have a glass or a bottle of mostly ice with some water in it, and a banana sitting on the front porch so I could just stop for a minute. Now that I'm diabetic, when I start getting more miles built back up, I will do this, plus have a blood sugar meter ready to go.
I really haven't run more than a mile or two since I became diabetic, though, so I might end up carrying the meter with me as I run. I hate carrying things, though. I have never even run with water. I went on a short run this morning and loaded up my sports bra with my pump, my ipod, my house key, and had my garmin on my wrist. I felt like a cyborg, not a runner!
