Today's guilt will power tomorrow's run

I wasn't feeling well yesterday and thought I may have caught a cold. Thursday's elliptical session wore me out much more than I would have expected. I bounced back last night and planned to do a run for this morning. When I woke up, I felt a little dizzy. After being at this for almost four years, I am able to tell the difference between being "morning tired" and actually feeling weak. I quickly decided to skip today's workout.

The main reason I opted for a rest day is that I hope to do a long run tomorrow at Bethpage. I didn't want to wear myself out on a maintenance run, and I thought some additional rest might be beneficial. I think resting was the right thing to do, but I'll admit to having some guilty feelings about it. I'm planning to use that guilt tomorrow to motivate me through what I hope will be my longest run (so far) this year.
