I have to do the same. I am in the same boat as you - the unnecessary risk catgegory. My wife can't stand it. I really should get a RoadID
Currently I run with my Garmin 305. That's it.
If I plan to be out for a while I take a couple of bucks cash as well. I'll adjust my route to run by a gas station, 7-11, WaWa, or QuickCheck or the park to buy water.
If I am in the 10+ mile range, A couple of honey stingers get jammed in the pocket of my shorts.
I rarely know the exact route I am going to take when I leave my house. I have a milage in mind, and I know the distance of the major loops, so I run around and check my watch every so often until I know if I turn around and take the direct route back, I will hit my milage (Sometimes I have to run past my house for a quarter mile and loop back to get the milage I wanted - I hate that). I have been known to loop around a large parking lot to make up a couple of tenths if I have to. Those runs are fun to look at on the Garmin track.
I really need to start running more trails. Since there are no 7-11's on the mountain (yet) I clearly have to start supplying my own hydration. I have yet to find something that I like. Everything is too "sloshy"
