The mountain bike world cup kicks off in Pietermaritzburg, South Africa this weekend, with qualifying for the downhill today.
According to Cyclingnews.com's race preview, the downhill course is 3.12km and "known more for the physical demands it places on the riders than its technical difficulty. A hard pedalling section in the middle called Khathala ("Tired" in Zulu) means that to do well requires power and endurance."
