Quite an interesting piece on how the your brain can play tricks on you. Whilst it is about running it applies to all training situations. It reminded me of a lecture I attended where Prof. Andy Jones, Paula Radcliffe’s exercise physiologist, talked about how they had tested Paula before all her best times. In each case the time predicted in the tests was within a few percent, less than 5%, possibly within 1-2%, if I remember correctly. I can’t help but think that being told she was capable of time X increased her confidence and belief in her training and ability to achieve the goals she had set.
