I was never one to waste a lot of time stretching, that is, until I got injured. I discovered that I wasn’t doing enough stretches and I wasn’t doing enough proper stretches to aid my running and to avoid injury. Here are some websites with some simple stretches to incorporate into your pre and post run routine.
