Lee and Cragg, definitely! I’d have to drive to Cannock, but I can do that ride from my front door 😀
Seriously though… I’d say given the present (horrendously boggy) conditions everywhere, Lee and Cragg are a better option, as they’re all pretty rocky, and hard pack, and so drain well. And the winds aren’t too high at the moment, so you won’t get blown across a pennine moorland.
Edit: If you’re coming from Burnley, then start at Lee, do the slog up to Cragg to start, have a good old play up there, then the brilliant link trail (you’ll just have slogged up) becomes a joy when pointed down it, then a play in the much rockier Lee.
If you want to combine it with more natural stuff, I can recommend some good routes to extend it from Cragg too
