This is how you should have felt last week- so perhaps faster speed- bigger hills- more effort put in? Then again perhaps you did not go far enough through the pain barrier. When it hurts- you just keep going and everything just fades away. Your butt gets so numb that you cannot feel it- The numb foot would have had no feeling in it, and the legs would have adjusted themselves so that the pain was in every joint and muscle- so you would have been able to sense which bit hurt the most so you would not have concentrated on it. Bit worried about the hand though- You dare not push them that hard as it will not be possible to eat a pie with numb hands.
