Hey. Last three times out I have hurt from the first minute to the last. My legs were killing me, my back hurts, feel like I have no energy, etc. The weird thing is that I continued to ride and actually rode very well and post ride analysis indicates that my power, speed, and heart rate were all great. I am not sick that I know of, and if I were i would think my performance would be down but it wasn't. . .

So, any ideas as to what is going on? Why am I feeling so lousy but still performing very well?
