Terrain & Elevation
The course covers a genuine mix of surfaces, with gravel (30%) and trail (29%) 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 5.1 km of trail. Ascending sections cover a varied mix of surfaces with no single type dominating the climbs. Downhills are spread across a mix of surfaces, with gravel most common.
