The route is marked with blue and white markers.
Starting point: junction of Place de la Gare and Avenue de la Gare in Gallardon (suburb known as Pont-sous-Gallardon)
(S) Continue without crossing the bridge towards Chemin des Vignes (Bailleau-Armenonville commune), which will lead you to Baillolet after 3 km. Take the D116 on the left and pass under the railway bridge. Then turn right onto the D330.
(1) Take a path on the right (the signposting is clear but you need to pay attention). After 2.5 km along a beautiful path, you will arrive at the very typical Beauceronne farm of Les Bordes.
(2) Follow the D329.1 to the left (view of the cathedral in good weather).
(3) 500 metres further on, turn right (signs are almost impossible to see) onto a tarmac path, towards the path that leads (signs are very faint) beyond the level crossing to the Bailleau-Armenonville gliding field.
(4) Turn left (west). You will reach another stream bed: a deep, game-rich Beauce landscape. After 2.5km, in Senainville, a detour signposted Rue Jacques Brière leads to Rue Pasteur (D19).
(5) Turn left and follow the D330.3, which offers a superb view of the cathedral. Be careful of traffic. At the exit, cross under the railway line.
(6) Cross the D32 and follow the road opposite for about 200 metres (be careful of traffic).
(7) A signpost indicates "right-left-right" in the middle of the field 300 metres ahead (bends on the rural road).
(8) Turn right. For nearly 2 kilometres, enjoy splendid views of the cathedral on the beautiful straight road leading to Coltainville - perhaps the highlight of the route. Take Rue de Pereuze on the left, then turn right onto Rue Jean Moulin, which continues as Rue de l'Eglise, leading to the beautiful church and its shaded, grassy square.
(9) To leave Coltainville, follow the signs for Rue de la Croix Buisée. 30 metres further on, turn right onto Rue des Tilleuls, which leaves Coltainville. The road leads to the foot of a railway bridge.
(10) Leave the road just before the bridge and take the path on the left. After 1 km, continue under the road bridge and stay along the railway line. Then another 1.5 km of beautiful views of the cathedral until you reach the entrance to Oisème, a small town nestled beneath the Beauce plateau. Follow Rue des Rabats on the left, Rue de la Chenaie on the right and, at the left-hand bend, Grande Rue, which descends and crosses the Roguenette. Exit via the D105.3 towards the west.
(11) Just before the sign, turn right onto Rue de la Gare.
(12) At the end, find (to the left of the wire fence) the entrance to the path running alongside the railway line.
(13) Cross the railway line at the level crossing, turn right (pre-signalled turn) and join the plateau.
(14) At the crossroads, turn left (view of the cathedral).
(15) Follow the cycle path to the left, then turn right under the road bridge. Walk along the gardens on a pleasant path. The signposts take you through Champhol for 2 km. The cathedral shows the way, with no visual obstacles, thanks in particular to a beautiful, perfectly oriented mall.
(16) Cross the crossroads (beautifully laid out) connecting Rue du Pigeon Voyageur to Rue des Grandes Filles de Dieu in a straight line. Continue along the D6.
(17) Be careful, turn left. The arrival in Chartres via Rue Hubert Latham is along the plateau, like a "landscaped balcony" overlooking the Eure, facing the apse of the cathedral: splendid! Enjoy the beautiful descent via a pedestrian passage (Trait d'Aboville, then Avenue Bethouart) towards the Eure, which you follow for 400 metres along Avenue du Maréchal Foch.
(18) Cross the Porte Guillaume on the right and continue along Rue du Bourg and Rue Saint-Eman (steep climb).
(19) Pass the Charles Péguy monument. Go up the stairs on the left just behind it and you will reach the superbly restored Place de la Poissonnerie. Take Rue aux Herbes at the end on the right: you will arrive in front of the cathedral facing its south portal (E).
