The Raid Corsica is a fabulous cycling challenge first set up by the Parisian Audax club, who also happened to think up the madness that is the Paris - Brest - Paris! Well, they know what it takes to make a fantastic cycling route, and the Raid Corsica or 'Tour de Corse', is a wonderful circuit of the island that is also known as the "Isle of Beauty". Ok, so another name for the island happens to translate as "Mountain in the Sea", but then what kind of Raid would be flat .
