Guide Book Publications and Runner World Magazine teamed up to provide a ranking system of South Africa's best races. Three years of data were considered – 2005, 2006 and 2007. For a race to be in the running, the event had to have been ranked for more than only one year, even if it was the top race in a year. The most important ranking consideration was therefore consistency. Each race here is a winner, providing athletes with a consistently well organised event. Each of these races is 'number one'.
