The most common thing mistake is to describe Corsica (or any other Mediterranean island) by comparing it to another island that we know better. Well, there's no bigger mistake. Corsica is not a Sardinia with something less or more as well as Sardinia is not like Sicily with something less or more. So why don't explain Corsica (and the other islands) for what it's got, and not for what it misses? Corsica has got fabulous mountains, very little or no flat (except on the eastern side that is less suitable for cycling).
Cycling in there gives an amazing feeling of freedom and challenge. You'll feel the uniqueness of cycling across Alps-alike mountains, with some of the longest climbs we've ever made, but immersed on a purely Mediterranean geography and weather. Not enough? Well you'll find there some of the nicest coastline roads too, especially on the stages along the west coast.
Out of the mainstream locations, roads are quiet and the asphalt is generally good. We're definitely sure it's an experience that a dedicated cyclist must do!
