Rode some of the blue route (and green, and red, and purple - real rainbow ride) on Saturday morning. Bit spongy at the moment, but once more wheels have been over it, it's going to be awesome (not that it isn't already). One or two nasty surprises along the way too, just to keep you going!
Did encounter some riders who were going the wrong way round, who claimed the signage showed they were meant to go that way. I think they were just not looking properly (I certainly didn't see any signage that could be confusing), but it's something to be aware of if you do plan to ride the route.
Is there an easy (legal) way to link from the new Blue route to the Yellow loop?
