Pretty good over here until you get into towns. Our Cuckoo trail is well maintained in general with patching done on bad asphalt and verges cut back to keep brambles away from the edge. Litter is not too bad but Dog Crap around residential areas is. Then you get into Eastbourne and at least the dog crap is not there but roots from trees are erupting in the path and the verges are not cut for about 3 months. Nettles and brambles along with Hawthorn growing over the trail do cause a problem and the debris from when they are cut is all over the trail.

That is why I prefer to ride on our back roads or offroad trails where you know what to expect round the next corner--Probably Cow muck as you have just followed the Farmer as he moves his cattle from field to field.
