I hate feelings

This week I have been training as always, well not as always, I had a coupla days off, although they were not the problem.
The problem has been the feelings. How is that possible that the day that I had made my 3rd best time yet I was feeling slow? there is a problem between my mind and reality. The but that has also happened teh they after, well that they I went a lil slower but it was still considered fast for my standards. Why does that happen? It is very annoying.
There is another problem and that is that I feel fatter lately, I'm not sure whether I have put on some weight or not but I feel like it.
And also feelings are not good when you compete, sometimes they can play tricks on you and overstimate on your performance and in a long distance race that is not good. You have to be cold and methodic, and don't let the feelings to interfere your plans.
I have also learned this week that on a time trial race like the ironman very step is important, a good start is as important as the end, and the lost time at one section is impossible to get it back later on when the fatigue kicks in, so it is very important to stay focused all the time.
