Thinking about a 70km or so road ride starting at Wiseman’s. Head out Singleton Road along the river, then up Laughtondale Gully Rd, then Old Northern/Wiseman’s Ferry Road all the way along to River Road (with a nice diversion), then along River Rd back to Wiseman’s.
Only big climb is the Laughtondale Gully, which has been resurfaced and is a beautiful climb through rainforest.
All doable on 25s (or 23s if you’re a masochist). Pace won’t be high, stopping to collect stragglers etc.
Reason for tarmac-only is I’ve got some mates who only have roadies but want some nice country roads to ride. But lets do a gravel/dirt ride sometime soon.
