PASTRANA-ENTREPEÑAS

Launch from the high plains of the Alcarria, near Pastrana, and terminate in the rugged embrace of the Entrepeñas Reservoir basin. The corridor slices through the Tagus River’s dissected meseta, a terrain of rolling limestone ridges and sun-baked valleys where elevation shifts like a restless operator’s mood. Technically, this is a slow, deliberate grind—punishing climbs into the Alcarria’s dissected uplands followed by brief respites in the Tagus’s shadowed gorges. Speed is a luxury here; operators will find no sustained rhythm, only relentless micro-adjustments as the route punishes hesitation with steep, winding ascents and abrupt, gut-wrenching descents into the reservoir’s drowned valleys. A route so unforgiving it makes a GPS recalculate its own life choices.
