The start and finish are at the town hall square in the commune of Lormaye, next to Nogent-le-Roi. There is a small free car park there. If there are no spaces, you will probably find some in Rue de la Mairie or Rue Alexandre Goislard, both just behind the town hall.
(S/E) Opposite the town hall, turn left, then immediately right into a tarmac road that continues onto grass. Go to the roundabout, then follow the D116, almost opposite. The D116 crosses the Eure.
(1) Just after the bridge, turn left onto the path that runs alongside the Eure. The river is now on your left. The path passes under a metal footbridge. Do not go up onto the footbridge.
Continue along the path until you reach Rue des Remparts, just after crossing a small bridge.
Continue straight ahead on this street until you cross the main street, at the church. Cross the main street and continue opposite, along Chemin de l'Abreuvoir. The path becomes narrow and each bend gives the impression that it is a dead end, but this is not the case. Eventually, you will come out onto Rue de la Ribordière.
(2) At this street, turn left. At the end, turn right to go uphill.
(3) At the crossroads, turn left onto the small path that runs along the wall and quickly joins Chemin de la Grenouillère, which is tarmac at the beginning. Follow this path for about 2 km without deviating.
(4) After the old Ruffin mill and its castle, stay on the left-hand path, which runs alongside the Eure. Continue for about 1 km. Pass close to a stud farm. The path branches off to the right and leads to a small bridge over a stream. The path then leads to the Boissy road.
(5) Turn left onto this road.
(6) After crossing the two branches of the Eure, take the path on the left. It runs alongside the Eure, which is on your left. Follow this path for about 2.5 km until you reach a tarmac road, the D306.3. Take Rue de Ruffin, almost opposite. Continue along this street until you reach a roundabout.
(7) Just before the roundabout, turn left onto Rue Max Cousin, which runs alongside a few businesses. At the next intersection, continue straight ahead along the street, which becomes a greenway for bicycles.
Follow this greenway for 600 to 700 metres, ignoring the bends it makes after about 400 metres of straight road. The greenway leads to Rue Maurice Gledel. Cross this street and continue straight ahead towards the centre of Nogent-le-Roi until you reach Rue du Général de Gaulle.
(8) Turn left onto this street, then immediately right onto the small cobbled street that runs alongside the church. Turn left so that the church is on your left and the market square is on your right. Cross Rue du Chemin Neuf and continue straight ahead onto Rue des Clos. This street continues along a small path between the walls.
(9) At the end of this path, turn left onto a similar path that crosses a stream. This path leads to Rue Alexandre Goislard. Simply turn left and then immediately right to return to the starting point (S/E).
