Terrain & Elevation
The course covers a genuine mix of surfaces, with trail (39%) and gravel (21%) 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.
Winter On The Downs 100 Mile has 57.3 km of trail / path, this is in the top 8% of all our races.
