I have often mentioned my dislike of tarmac and other hard surfaces. But living in Leicestershire, I can't always get to real fell terrain, and so I do peruse various trail-running websites to see if there is anything suitable for my preferences. Just occasionally, I do find something that looks good.
The Ambles Revenge at Oxspring (near Penistone) looked quite good https://racebest.com/races/46u75: but the more I study the route, the less good it looks. There is not too much on public roads, but the Trans-Pennine Trail is a hard surface, and there are also substantial sections on farm tracks that look like they may be too well surfaced for my liking.
Then there are the trail races at Staunton Harold https://www.endorphinsport.com/10km-...-run-canicross. I could cycle to this place within an hour from home, and it has great potential for a varied race across rough grass and woodland paths, and there's that lovely steep slope on the east side of the estate. The course does go through the woodland, but as far as I can see from the satellite view on Google Maps, the route is mostly on hard-packed vehicle tracks and road (most of it is not public rights of way, so I haven't recce'd it, although I may go for a little trespass some time); and it keeps off that steep slope. I don't think I am going to be paying £24 for the privilege of running a rather uninspiring 10km.
I suppose, if I was desperate for some off-road racing at this time of year, I could re-join Charnwood AC and run in the North Midlands Cross-Country League, but somehow the idea of running laps round Berry Hill Park (Mansfield) or Markeaton Park (Derby) just doesn't appeal to me any more. The best non-fell races that I have found seem mostly to be little events organised by someone in a village who wants to raise money for a local charity, and which I only find out about when I happen to see a link on Facebook (because that's the only place they are advertised): Gaddesby Gallop, Hoby Hop, Higham Hill Race.
