Every runner knows the feeling. Whether it’s a nagging knee or tight hamstrings, it seems like pain comes with the territory of being a runner. Some even wear it as a badge of honor. It doesn’t have to be this way. Although the warrior mentality many runners possess is admirable, it’s not always smart to push through the pain. There comes a point when pain becomes an injury, and that can leave you sidelined for longer than you’d like. Before you head down the recovery road, it’s important to know the signs and when it’s time to back off your training.
