Did 20k to finish off May's distance goal of 700k on Monday and did another heavy power day. The best way I can describe the suffering and pain I voluntarily inflicted on myself is to say I went into the hurt locker, slammed the door shut and bolted the door behind me. At one point, I literally had to consciously tell my legs to move.
They were so locked up with lactic acid and sending signals of agony to my brain that I had to consciously concentrate and focus on first my left leg then my right to get each to move. If I wasn't thinking about the leg it was dead weight and did no work. A painful, flaccid piece of useless meat and bone. My brain simply refused to send a signal to that body part. There was no reflex or momentum or automaticity. Man my legs hurt.
