Tomorrow the last 50 km are flat, so the only factors which can avoid a pure mass sprint are the wind or mass falls.I'm not sure. He's been pretty low key about his chances and admitted to not being at his best yet (which is understandable)... but if it's raced fairly easily and he's delivered perfectly to the last 300m then he's always got a good chance. I think Philipsen will get one anyway. Ewan seems in good shape too.
At stage 5 we have 20 km away from the finish the Kerby hill with 1,6 km and 8,7 %. Perhaps there he could be dropped...
