Shortly after this point I realised that the trail had bypassed the Crown Range Road and had to backtrack into a head wind for around 10km.
The Crown Range Road is spectacular. It starts straight away by throwing 5 impossibly steep switch backs in the first 2km where it rises around 300m. It is then a steady steep climb for the next 5 or so km before more switch backs up to the pass at 1067m, which is the highest paved road in New Zealand. It is then a very fast (and cold) decent down the other side. I manage to get the trike to 75km/h but I did have to keep the speed down because of the corners.
I spent the night at the historic Cardrona Hotel, which was expensive but very comforting after the ride.
