Giants Challenge
 |
The Giants Challenge is a tough one-day mountain-bike marathon held in April in the rugged and picturesque Giants Cup area of South Africa's Drakensberg Mountains. The course is 75 kilometres of tough and stunningly beautiful terrain through the uKhahlamba Drakensberg National Park, a World Heritage Site, and is widely regarded as one of the toughest of South Africa's MTB marathons.[citation needed]
Riders take between four and nine hours to complete the challenging course, which includes several kilometres of compulsory portages, insanely fast downhills and wet river crossings through icy rivers.
