The Rector of the Academy of Physical Education in Poznan, the Mayor of the City of Poznan and employees of the Athletics Department of the Academy of Physical Education invite to an open lecture by Professor Timothy Noakes (South Africa), a brilliant scholar investigating issues related to long-term physical effort, especially marathons and ultra-marathons, as well as to human physical capacity under extreme conditions. The Professor is himself a participant of 70 marathons and ultramarathons and the best-selling author of ?Lore of Running?, often referred to as the ?Bible of Runners?.
