The Crater Cruise attracts not only South Africa's best mountain bikers, but also it's top road riders. More than R190,000 in prize money is up for grabs, with the winner of Saturday's 105km marathon taking home R45,000. Robert Hunter (Phonak), Ryan Cox (Barloworld), and Under-23 champion John-Lee Augustyn (Konica Minolta) are among the roadies who will race. Hunter's fitness and experience racing the cobbled Paris Roubaix make him the man to beat on the corrugated gravel roads that comprise much of the race course. At least 2000 racers will participate in various events associated with the Crater Cruise.
