From ASO site:
The drivers and riders will face 720 kilometres in the next few hours in what will be the longest stage since the start of the 2013 Dakar. The difficulty goes up a notch. This stage is a beefed-up version of the one that was run in the opposite direction in 2012, wreaking pure havoc. The route will be slightly different for the cars and the motorcycles, which will have to visit the three refuelling points in their road books. One of them comes 173 km into the special. They'll also tackle a 2 km slide downhill in the first third of the special. All in all, another momentous stage in this rally. The big favourites Despres, Peterhansel, De Rooy and Patronelli (most of them winners in 2012) took the lead on Monday, but their margins are still small and there's no doubt that Tuesday will be a very eventful day.
