Legs?

I woke up today and was thinking my legs didn't feel nearly as sore as I thought they would. Then I had to go to studio... I went outside and was walking down the stairs when I noticed I could feel my legs more than I had been able to... Then I jumped on my commuter bike and yep, I could barely pedal it downhill...
Later I went out to make an attempt at some sort of recovery ride. I averaged 14. The guy riding his fixie in a thong passed me.
