The same happened to me this morning, I could barely get throug the swim, then at the velodrome, it started to rain, which I was sooooo thankful for, so we didn't ride, and when we got to the track I did 2 loops and then had to walk, coach asked what was going on, was I down, and I said no, just didn't have a drop of energy to get me going...had already eaten breakfast, slept enough hours, so I quit and came home and slept two more hours...but still feel weak, listen listen listen to the body. We do this cause we love to, if our mind OR body says no, it is fine.

As soon as it is forced...well, not as much gratification. I get up every morning EXCITED to go train...so if I can't do it, I had better listen. Although it sucked to not train well.
