total prize purse at the 2013 Kimberley Diamond Cup was R5,000,000, approximately $500,000 in US dollars at the time, and was the largest single-event prize purse in skateboarding that year. During the summer of 2013, professional skateboarders Ryan Decenzo and Adam Dyet joined the WSGP's Skateboarding for Hope tour in the Northern Cape province and participated in skateboarding clinics and demonstrations in Kathu, Kuruman, Postmasburg and Kimberley. American professional street skateboarder Nyjah Huston won the Pro Street Contest at the Kimberley Diamond Cup, and $100,000 in prize money. Huston's highlights included a nollie heelflip backlip, switch frontside blunt, fakie five-o on high flat bar. Huston has been called "the best contest street skateboarder in the world" and is a 4-time X Games gold medalist. During practice, Huston was filmed performing a 270-degree "kickflip lipslide" on a rail, a difficult skateboarding trick that had never been on a full-sized handrail. "Vert legend" Andy MacDonald won the Vert/BigAir Overall (combined results from 50% Vert and 50% Big Air competition scores). MacDonald holds the record for the most X Games medals in vert skateboarding and was crowned as skateboarding's World Champion nine times in the World Cup Skateboard Series.
