Gav – the blue does what it should, competent riders will get a fair bit of speed out of it but there’s nothing much to intimidate beginners. Best thing would be to ride it yourself first so you know where stuff is – also, check a map, because there are plenty of places to leave the trail and return to the car park via fire rds. The blue makes good use of the gradient, there are no sustained climbs but there are a couple of relatively steep, non-technical bits both upward and downward. There’s also a series of descending switchbacks just after the halfway point. The reds split off from the blue at a couple of places, usually a step or gate to alert you to the fact. Apparently they’re opening it on the 3rd now, but some bits aren’t quite ready and will be fenced off.
