So I spent just over 3 hours there today and had an absolute blast. Its nice to know my legs and Explosif easily beat kids with all the gear and no idea.
Its very easy to get to from Martins Heron; took just under an hour from Waterloo. There looked to be tons of parking for those with 4 wheels.
There are 3 courses, the 1st very short for families. The intermediate took me about 25 mins to complete but add in the red route and you have a good 90 minute loop.
Theres a real mixture or terrain, the majourity is packed hardcore. Its got a big variety of singletrack. Highlights were the labyrinth in the pine trees (very narrow, very twisty, loads of roots), this sort of corkscrew thing in a big ditch (really tricky to keep the speed up so not to fall off or out!), and an excellent series of berms over a 1 to 2 mile stretch.
I think this would be a good, easy place to meet for a rb ride. Sure it doesn't have the vibe of a normal ride but it left me buzzing.
