Well finally I found the time to do a 100k ride, although my bottom probably wishes I hadn’t. From Pola de Siero the route heads seaward to Villaviciosa on the AS-113. From there you connect to the N-632, direction Colunga. Although it is possible to follow the N-632 all the way to Colunga I took the AS-257 via Lastres which was well worth it as it offered some great views. Before turning to Lastres you climb the Alto de Buenos Aires. This is an easy climb with an average of just 3.6% lasting 4.8km.
Lastres & Colunga
From Lastres I continued to Colunga passing the lovely Playa La Griega. This is a great beach and is famous for the dinasour prints that can be found imprinted into the rocks on the beach.
Once at Colunga I turned right back on the N-632 and then left onto the AS-258. This road starts off fairly flat but after several km’s you begin to climb the Alto de la Llama, a 7km, Cat 2 climb with an average gradient of 5.3%.
This is a really nice area to ride with very little traffic and some great views.
Once you complete the descent of the Alto de la Llama you come at Villamayor and connect to the N 634 which takes you back to Pola de Siero. it’s approximately 40km back to Pola but the road is relatively flat all the way back.
