Terrain & Elevation
The course covers a genuine mix of surfaces, with trail (37%) and grass (20%) 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 trail, though the surface varies across the ascents. Descents cover a variety of surfaces with no single terrain type dominating.
