Cudillero Marathon

Asturias / Cantabria • Start/finish: Cangas del Narcea • Distance: 240 miles • Riding time: 6.5 hours • There's so much to see in the Picos – not just the famous roads around Potes (great as they are). This day in the Asturian mountains is packed with passes, gorges and epic views, heading down to the beautiful seaside town of Cudillero then looping back inland on mind-bending roads. It's a long ride, but there is also a shorter version available.
