As a complete newbie to trail centres and Coed Llandegla my impression is that the blue is a nice warm up, red is a little longer (1 hour steady) and not too technical. Black is doable on a 100mm hardtail, granted I did miss part of the first black section, and is what I would classify as not too technical cross country as in you need more fitness than technical ability and is doable at a steady pace in the 1.5 hour mark.
I didn’t see anything that requires a FS, body armour or a full face helmet.
You will love it or hate it depending on your expectations. Gnarly it isn’t, fast and lung busting it is.
Me and my jeyness have embraced it. 😀
I kind of think it would be a good place for an STW informal weekend meet.
