Week 7 - Day 3 Tempo Run Bonked

I am tired. And I bonked, this run. I was supposed to go 10k distance and really hit the wall at 8k. My cardio was fine, in fact I found that I was breathing very steady and easy, it was my legs that quit on me. And looking back at my training log, I'm at the crest of overtraining. The Week 7 Day 1.5 LSD run with Osty and Rob really killed my legs with running in what felt sand. The other issue I had this day was I worked from 1-6am, got home and slept until 9am and couldn't go back to bed so I was pretty sleep deprived.
