If you get a stress fracture your first question is probably whether not you can just keep running.
Before you can answer that question, you have to figure out whether or not the particular stress fracture you got as a consequence of over training is a high risk stress fracture or a low risk stress fracture.
If there's a high risk your stress fracture is going to break, you may not want to run on it.
If there is a high risk your stress fracture just won't heal if you run on it, and you probably want to back off.
Today on the Doc On The Run podcast, we're talking about what makes a stress fracture high risk for a runner.
