Tell me lies, tell me sweet little lies...

So here's a new race strategy for you - deception.  In an article published in the New York Times, scientists explained that they found that athletes that were deceived into believeing that they were performing below the level that they were actually performing were able to reach beyond previous limits.  The article explains it more in depth, but basically they found that we can be tricked into going beyond our physical (or actually mental) limitations, simply by not knowing that were are crossing that line. 
This may come as no surprise to coaches who have been using this tool for ages (that damn Corss Country coach who said the finish line was "just around the next turn"), but might it have some utility for those of us who train ourselves?  Perhaps not knowing our time or distance in a workout could allow us to go beyond our preconceived "limits" - using ignorance as a form of self deception.  Can you fool yourself into breaking records?
