See above a picture of the slightly revised route, this time we go the short way around Lake Munmorah. There is no sign at the turn off (which is why we missed it on the test ride last year) The turn is just at the 120km mark, for those with Garmins etc.
To download the course to your Garmin (if you have one) follow the link below….
newcastle overnight 
there is a back way / shorter way through west gosford / wyong that will get you to doyalson saving a few k’s and definatly several hundred metres of climbing
err forget the last post, i was wrong, it saves about 10k, but only 60odd metres of vertical elevation
Are you able to post a non garmin connect route? Apparently GC doesn’t allow exports anymore
