I leave myself a message on the home phone when my husband is out of town. That way if I don't turn up, someone might eventually know where I headed last. Not the best solution, but cheap. I also keep the ranger number in my cell--hunters are allowed in the wildlife area I used to run at. Occasionally, I ran into a bow hunter that creeped me out. Also, if I get hurt--I figure they are closer than the ambulance. I'm sure they won't mind you checking in--they may even have suggestions on routes!
