It could be your shoes as well. I've been running for a couple years, and take frequent breaks now.
Vary your run; do different distances, speeds etc. But don't neglect shoes; indulge in a new one every 500 Km.

However, I would be willing to buy shoes like the vibram 5 fingers to protect me from the occasional pebbles and the dangerous glasses but not modify how I run barefoot.
