There are plenty of reasons why runners break.  The human body is a fantastically robust and adaptable organism, but it has it’s physical limits that, despite our good intentions through hard and long runs…can often lead to injury.  The problem is that our willpower is often far stronger than our bodies power to absorb stress.  
You have within you the power to accomplish great things, and run impressive races…while at the same time you have the power to run yourself into the ground, and break that body that you’ve been fortunate enough to inhabit.
Always remember that our human bodies are amazing pieces of equipment but compared to the surface of the planet, they are just small squishy things…and you know what happens when you take a small squishy thing and throw it at the side of a mountain…it squishes.
Don’t squish yourself.  Run long, fast and hard…but never over the physical limits that mark your own structural integrity.  Your body can do great things, but not if you abuse and overuse it out here, on the road.
