It needs more fitness and is an XC trail not an enduro trail if that makes sense. Also fun but I almost died (well it felt like it) taking a 160mm LLS bike round it (and trying to keep up with folk on hard tails).
This is something to bear in mind, and is probably the main reason why so many folk moan about Dalby. Short travel full sus or hardtail is the best for the red trail.
My usual route is to park in the big car park by the bike hub, do the red until Dixon’s Hollow, have a mess about on the jumps for a bit, then do a lap of the black, then get back on the red and follow it all the way back to the car.
