I think Cannock is the last place I would ride again. Not because the trails are poor, they aren’t. Just the general feel of the place. It’s not welcoming and, without trying to be snobby seems full of twunts. In fact I would prefer to ride at Swinley than Cannock now and that’s saying something.
That said my advice would be to consider timings. The FOD blue gets horrifically busy on a Saturday/Sunday. Maybe go earlier or later in the day. That way you will avoid the majority of the full face Capra squad buzzing and swearing at your kids because they ruined their Strava times.
