Forgive Me For I Have Sinned...

I was supposed to run 1 hr and 10 min this morning, which amounts to approximately 8+ miles, but for what ever reason, I just couldn't do it.  Ended up running 58 min and 7.1 miles.  This is the first time I  wasn't able to complete a training run.  Be it the humidity, the lack of sleep, or the fact that the watch battery died at 6.65 miles, I just didn't finish.  This will bug me for the rest of the day.  I'll have to tack on 12 extra minutes to tomorrow's run to get the miles in, even though it's a completely different kind of run.
