Mudy but probably not high on the Swinley Bog Index yet. It’s been dry for some time and has been holding up well. Depends how much more rain we get though and Swinley does have a lot of high traffic.
Stick to the hard packed trails and it shouldn’t be so bad. Crowthorne side tends to be more muddy, and the new sections of Stickler need bedding in and turn to glue in the wet. There are signs up from the trail builders asking people to not ride it in the wet at the moment.
Riding with others though is the best way to find the trails. Been riding there for 4 years or so and still find bits I haven’t done before, especially if someone new knows that bit. Loads round Crowthorne side I kind of knew but hadn’t linked it up, but following someone who knows the Gorrick courses the other day made it all link up perfectly. Just got to remember it now!
Check out some of the rides on Bike Radar, MTBB forums amongst others and can hook up with rides. Tend to be weekends though 😉
