This is essentially a 'night fell race'. The terrain underfoot is varied. Although it does have some stony sections, the majority of the route is on good paths and tracks. It is not what I would describe as 'technical' at any point, but running on this terrain at night will raise the level of 'challenge' for many.  You will need a very good torch (preferably headtorch) to both see the markers and the ground beneath your feet.

The way will be marked with reflective arrows and ground markers. These do not give out their own light but do reflect back the light from your torch. You will not need to use a map if you stay on the marked route. There will be around 200 reflective markers placed. No navigation is required.

A significant section (around 2kms) of the route traverses on flat ground at the top of the steep north face which in good weather will afford great views of Abergavenny at night.

We start and finish as for the daytime Blorenge Fell Race, 100m from the village hall just over the Abergavenny to Blaenavon road. A short section of road is followed by an ascent of the 'incline'. After a field or two we head off right (west) on a rugged footpath. This ascends gradually and eventually leads you to the old tramroad underneath the summit. A flat run of nearly 2km follows, leading to the flat grassy ledges of the old quarry. Just beyond the 'blockhouse' we start to descend on a grassy path. When we hit the road, we head back east on the bridleway which is stony in places. We run around the lake at the punchbowl and then comes an undulating path back to the fields after the incline. Down the incline to the finish.
