GT20 Étape 10: Grosseto-Prugna – Casevecchie

Leave seaside Grosseto-Prugna by the Gulf of Ajaccio and climb into Corsica’s interior toward Casevecchie. It’s a punchy ride: about 45 km with roughly 2,600 m up and the same down, mixing long ramps, tight bends, and big views. Mostly on road and can feel busy in spots, so stay alert. You’ll roll into the quiet hamlet of Casevecchie, a world away from the coast—perfect place to catch your breath before the next GT20 push.
