Roll out of Secugnago and follow the Lambro river before the route slips into the Parco dei Sillari nature reserve. Next comes the Parco della Collina di San Colombano, then a pause by Villa Braila manor, and on through the Parco Adda Sud nature reserve. The loop closes past Palazzo Calderari castle and back to Secugnago, with 69.6 km and 180 m of climbing along the way.
