Marathon runners inspect the route for the eighth Great Wall Marathon, at the Great Wall of China in Kuaihuolin, China, May 17, 2007. The Great Wall of China is among the leading contenders to be the new seven wonders of the world as a massive poll enters its final month with votes already cast by more than 50 million people, organizers say. The seven winners will be announced July 7, 2007 in Lisbon, Portugal.
