Two sections of road, each over 1 km long, at the start and finish, are very unpleasant, stressful and even dangerous, and should not be attempted with children. There are no facilities for pedestrians; you have to walk along the side of the road, which is not very wide and quite busy. Special mention for the arrival on the D15, where you walk along a sloping embankment with brambles, with cars passing at 70 km/h just 50 cm from walkers
