Exhausted

Yesterday I did a 8.5km run at my dad's house. It was a good clean run. Not easy but not hard. The time went by fairly quickly. But today I woke up after 11.5 hours of sleep absolutely exhausted. This feeling came with me to the gym. I ran at a much slower rate and had about 3x as many walking breaks. I did a short run and followed it up with the wave and elliptical machines. It was a tough cardio day. The rest of the day felt just the same. I hope tomorrow I'm feeling a little more with it.
