Energy?

Today's Run:
On treadmill
Max HR 191
Average HR 151
Speed 3-6MPH

I just didn't have it in me this morning, and like I mentioned it's probably all in my head. I just felt like I couldn't do it today :( That's okay though I'll have a stronger run next time. My diet has been way off for a while and I'm sure that doesn't help either.

Today I walked .25 of a mile and then ran 1 mile then walked .25. I think I'm just going to add to my run distance every time I run until I'm at 3.1 miles. The race is in about a month so I need to get up to it quick, it makes me nervous.
