Terrain & Elevation
The course covers a genuine mix of surfaces, with paved road (31%) and trail (25%) being the most common and neither clearly dominating. 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.
