In the 2nd century B.C., the Roman Empire encountered strong resistance to its rule in the province of Lusitania, embodied by an Iberian warrior named Viriato. While various historical accounts exist, the prevailing narrative suggests Viriato started out as a shepherd, later becoming a skilled warrior who led numerous revolts, challenging the supremacy of the Romans.

During this period, the province of Lusitania encompassed a significant portion of the southwestern Iberian Peninsula. Some historians place Viriato's exploits in the Sierra de San Vicente. Connected to the central system, this mountainous range hovers around 1,300 metres (4,200 feet) between the Tiétar Valley to the north and the Tagus River to the south.

The Viriato Trail (GR 63) illuminates the paths, landscapes and villages scattered across both sides of this mountain range. Spanning 165 kilometres (102 mi), the trail beckons mountain bikers to journey through meadows, oak and chestnut forests, to discover medieval gems such as stone bridges and hermitages, and to revel in the charm of quaint agricultural communities.

This Collection consists of three stages undertaken in a clockwise direction. The start and finish are in Navamorcuende, a small village nestled in the Tiétar Valley of Toledo, which is easily accessed by bus from Madrid's southern station. If you choose to drive, there’s parking along the village's streets.

The trail winds along trails, dirt paths and occasional paved segments of secondary roads. The most significant ascent, the Piélago pass – a renowned cycling classic in the region, offers panoramic views of the Tajo Valley. Aside from this climb, the route generally poses no major physical challenges. The technical aspect is also manageable, featuring an enjoyable descent along a trail from Piélago.

An ideal companion for this adventure is a lightweight dual-suspension mountain bike with a dropper seat post, allowing you to ride fast and still have plenty of fun on the trails. Prior to setting out, check your bike is in good working order and carry a repair kit and essential spare parts with you.

Each stage traverses a diverse range of towns and finishes near accommodation. This means you can travel efficiently and savour local delights. Remember to pack a waterproof and sunscreen.

Spring and autumn offer the best cycling conditions in the Sierra de San Vicente, when temperatures are pleasant and the landscapes are at their finest. Although winter is relatively mild in this region, pockets of frost might appear in shaded areas. Conversely, summer is incredibly hot in the valleys.

May the spirit of Viriato accompany you as you navigate the landscapes he valiantly defended against the Romans.
