I thought Simon Pavey's son, Llewelyn, had been accepted to race the 2013 Dakar, but
Story on Llewelyn riding the Taklimakin Rally here
edit: I noticed that the winner of the Taklimakan Rally gets to race the Dakar, though the article I saw didn't specify whether it was the 2013 or 2014 edition.
Upon release of the 2013 Dakar acceptance letters, Llewelyn was one of the unlucky few to be refused a place in the next edition of the race. . . . Left with nothing to aim for until next year Llewelyn quickly began to look for another event to compete in that would gain him further experience and as the Taklimakin Rally is one of a series of Dakar Challenge events it became a target of his attention.
I suppose that a handful of those initially turned down might yet be offered a spot as they become available (as with those in Jenny's situation deciding to not race, or as a rider is lost to tragedy, like with Kemal). So maybe Llewelyn will yet ride the 2013 Dakar.
