Head over the ridge, south of Tervuren and towards Hogaarden and Linden. Then pick up the L127 to Bertree (possible turn around point here, picking up the track back, giving a ride of 128k). Descend and climb just before the mid-way point. The reutn leg is alittle lumpy, but generally downhill. Evading Hannut town centre, join the RAVeL at Orp Jauche, Jauche to Happaye, Grez Doiceau, down Smeysberg and back to Tervuren
