A trip down memory lane chaperoned by Thomas Hobbes. We tour the first graphs of training principles. We quest for the Holy Grail of endurance athletics - the one true physiological model which will finally pull the personal best time or that six watts per kilo FTP from the stone. Have you ever felt something real and been told you were imagining something? What if I told you you aren’t crazy. This is a safe space. The path to glory is drowned in the blood of a billion blood lactate tests. The king is dead. Long live the king.
