Terrain & Elevation

The course is mainly trail (54%), with grass (25%) making up most of the rest. 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 10.9 km of trail. Uphills are predominantly on trail (68% of ascending sections). Downhills are spread across a mix of surfaces, with trail most common.

Black Beacon 100 Mile has 77.9 km of trail / path, this is in the top 1% of all our races.
