6mph is a lot harder than 4mph

This one felt like my hardest run so far.   I was working on a 10 min mile, which is a jump up from what I usually have done.  The quote came to mind, "your body can do it, it is your mind you have to convince."    I got a training schedule last night and was surprised that it has me running like 4 days a week!  The runs aren't too bad, the worst for me is getting up in the morning earlier.
