Bump -
ExPat - That's a very limited site for rides.
IMO, the Royal National Park is really a warm up and shouldn't be used to run too quickly, too many tourists and coppers, not to mention slippery bits early in the day with leaf litter and moss.
From Stanwell Park there are some great roads up to and back from the Southern Highlands, but it just depends on how far you want to go in a day.
City Coast Rat Pack are doing a few rides over the next few months as well. Might be worth a look see.
City Coast Rats
I'm at Engadine, right near the Nasho, but haven't got a lot of riding time over the next couple of weeks. Early December I'm free though!
