The terrain is highly fragmented, switching roughly every kilometre. This demands constant mental engagement and limits the ability to build a sustained rhythm from surface consistency alone. Climbs are mostly on gravel, though the surface varies across the ascents. Downhills are spread across a mix of surfaces, with paved road most common.
