The longer 55 kilometre route is a demanding blend of single track and technical challenges on rock and through river. There are climbs and difficult descents, in fact everything for the hardened mountain biker. The shorter 25 kilometre route is well liked by novices and is a lot easier. Here you will find district roads with a smattering of single track. There is a water crossing to add a bit of colour. These are interesting urban trail routes in and around the Kyalami Grand Prix Circuit, and unexplored northern Johannesburg areas.
