Treadmill.What does that word mean to you? Does it excite you? Make you nervous? Can you not help but cringe a little? I’m the cringer. Treadmills, to me, seem inadequate. Why run inside when we can run outside? Yet there are many reasons (yes, me included) to why runners need to hit the “dreadmill” every so often, some even more than others. These reasons might include: time, children, safety, preference or even because your coach has told you to.
