That's how I'm feeling right now. It's 5:45 in the morning. I've had my first cup of coffee. I can *barely* keep my eyes open.
It all started last night. I had an eight mile general aerobic run on the schedule. I wasn't pushing too hard. Just a nice run. Heart rate was low in the aerobic range. It was cool out. Everything was going well. I got the "out" portion of the run done and turned around to head back.
Hmm. No wonder everything seemed so perfect. I had been running with the wind at my back. Okay - no problem. Put my head down and push a little harder. My Garmin was telling me that my heart rate was at 3.1 - low in the aerobic range. So no problem if I cranked my heart rate up to a 3.4 or 3.5 (aerobic range on my Garmin is set to anything between 3 and 4). I pushed a little harder through miles 5 and 6. Then it happened. A feeling I haven't had in about a year. The last time this happened was about mile 17 in a little jog I took last June. I was done. Toast. Empty. Nothing left in the tank. (I'm trying to come up with a few more trite analogies, but I'm drawing a blank).
The last two miles were *really* tough. I kept my legs moving, but each step seemed like I was lifting concrete shoes. It felt like I was working *really* hard. My heart rate was still down though, and I wasn't breathing exceptionally hard. I had just run out of fuel. I so wanted to give up and walk it in. But, I kept putting one foot in front of the other and my legs moving. I ended up completing the run in 1:19:02 (9:54 pace) and an average heart rate of 76% of max. But I was spent. I had to collect myself before driving home.
The real comedy started when I got home though. Obviously what I had done is just not eaten enough during the day. I was *ravenous*. I grabbed some dinner (BBQ'd Tri tip, wild rice, steamed veggies). I sat down, turned on the Cavs/Magic game, and promptly fell asleep! That's right folks - down for the count at 7:30 PM!
On the schedule today - rest. Total rest. (Sigh of relief)
