The Richtersveld Transfrontier Wildrun is a five-day long, stage race that takes place in a remote region of South Africa each year in June. The 2015 edition of the race actually crossed the border into Namibia as well, covering some 200 km (124 miles) along a course that was both incredibly difficult and beautiful at the same time. In this video, you'll get a chance to see what the Richtersveld is all about, as we go out onto the course with runners who are pushing themselves to cross some of the toughest terrain imaginable.
