A South African woman drives a 50cc mini motorcycle past an Audi R8 during the 2013 Kalahari Desert Speedweek at Hakskeenpan, Northern Cape of South Africa yesterday. The Speedweek sees motorsport enthusiasts gathering in a remote desert in the north of the country to drive their vehicles across seven kilometers of specially prepared clay track for high speed top end runs. Technically the desert Speedweek is more challenging than Tar Speedweek and requires much more driving and engineering skills for top honours in each class including cars and bikes.
