For the serious runner, an injury that causes you to halt the activity that you love, can be a pretty frustrating experience. But if you push the limits often, injuries are bound to happen, and right now I’m dealing with it. Across The Years 48-hour run has left me with a sore knee/leg that really taking its time to heal. I drive down the road and see happy, healthy runners going by, looking at them in envy. But I tell myself, “rest is good, be patient.” Nevertheless, I have nagging irrational thoughts that my competitive running days may be over.
