From Mézin, the route follows a rough, unsurfaced greenway along a former railway line. After Sos, you need to cycle along the busy RD676 road for some 2km. This is followed by a stretch of 12km going via quiet rural roads with little traffic, but which are steep, taking you past agricultural fields as well as pine forest, up to the bridge over the Rimbez, where the counties of the Lot-et-Garonne and the Landes meet. Signposted EV3.
Surfacing smooth: on the stretches with asphalt and compacted tracks.
Surfacing rough: after Mézin, the greenway consists simply of rough surfaces.
