The Need for Recovery

More is better, isn't it? If four fast intervals at 10K pace is good, then five at 5K pace must be better. If the coach calls for 10 miles, doing two extra miles has got to be better. This is trap many of us get pulled into, especially when we aren't seeing results. "If I just put in my time / effort..." 

This approach will actually hamper your performance and possibly lead to injury.  It is important to follow your plan.  When the plan calls for an easy day, go easy.  Recovery allows your muscles to heal and grow. When it calls for a day off, don't workout.  Enjoy it.  With a little recovery, you may just get faster.

Train safe!
