Heist of Berg to six hills around Löwen

Cycling route in a loop shape with the racing bike from Heist to the hills around Leuven and the Hageland.
Starting from Heist op den Berg, through Keerbergen and Boortmeerbeek, along the Mechelen-Leuven canal, via Buken to Veltem-Beisem, Winksele, Heverlee, Kessel-Lo, Holsbeek, Kortrijk-Dutsel, Gelrode, Aarschot, Begijnendijk, Booischot and back to Heist op den Berg. In the southern loop around Leuven, there is enough relief to train the legs!
