Dalby Forest is closed due to the snow. While you could probably get round bits of the trails on your mountain bike, be advised that if you did have an accident the emergency services might have trouble getting you out. So think carefully before heading up there. Given the dismal forecast, it’ll probably be some time later next week before it re-opens. But we’ll see.
Note that the bad weather is also curtailing many of the club rides at the moment, off-road and on. The main roads are passable, but it’s slippy in places. I felt the back end of the bike start to slide yesterday on a black-ice corner.
Take care out there. Or learn to love that turbo trainer!
