Exactly the feedback I was looking for. A small gun is probably doable, but some of these runs are 5+ hours and self sustaining, so weight and bulk are issues vs threat concern. My wife worries about safety as well and leans toward lethal vs nonlethal alternatives. I have never had a concern on the road or trail, but better prepared than not. I can always exit, but a late night drunk or even an animal could be an issue. perhaps both items could be accomodated, but perhaps running partners might be a better idea.
