Today will be 120 years since the birth of one of the greatest runners of all time – Finnish Paavo Nurmi. Nurmi was born in Turku, Finland, and every year on June 13th Paavo Nurmi Games will be organized in Turku in the memory of Nurmi. This track and field event is now part of the IAAF World Challenge -series and has attracted many world-famous athletes to Turku, such as pole vaulter and current (indoors) world-record holder Renauld Lavillenie and leading javelin thrower Thomas Röhler. In addition to the current stars and games, also Nurmi’s training and life can teach us a lot about world-class preparation and improving fitness.
