Okay, today's run was just awful. And I don't know why.
It started off okay. 12 mile long run at sub 8:00 pace. No real problem for the 1st seven miles, where I averaged 7:57/mile (granted, all over the map in terms of pace, but still ...). And that was with very challenging conditions. Mainly freezing rain, and the roads were like a skating rink. I did my best to stay in the crusty snow off to the side, but not easy running. A bit of a headwind too.
Then it was like I just ran out of fuel. NO pep in my step at all. I had to slow right down, and that was now with the wind at my back. Ending up running almost a minute slower/mile. Decided to cut off a mile (since I could) and ended with an average pace of 8:13. Knees - sore. Ankle - sore. Stomach - felt awful. It was even hard to walk at that point - not from pain, but from exhaustion.
So, I'm not sure what went down. Maybe overtraining a bit? Nutrition off? Too much wine last night? Started off a bit too fast?
It's 4 hours later and I've had a nap, and my legs still feel like rubber, so I'm going with the overtraining theory. I think I'll see if taking an easy week - no speedwork - helps.
