Terrain & Elevation

The course covers a genuine mix of surfaces, with trail (48%) and grass (22%) 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. The longest unbroken stretch is 9.7 km of trail. Climbs are mostly on trail, though the surface varies across the ascents. Downhills are spread across a mix of surfaces, with trail most common.
