Putty baby!!!I know it might *seem* sorta long, but you can pull it off in 5 hours including a few stops (shorter if you do speed limit + GST [moto]). The surface from Colo River up the hill to Halfway has just been resurfaced and it is in awesome condition. Ditto the 40Km run from Halfway to the Broke Turnoff (this is actually one of the best, twistiest bits of road that I have ever ridden on).
A) Start Wilberforce Caltex
98.5 km – about 1 hour 16 mins
B) Halfway (Gas for testas)
42.4 km – about 34 mins
C) Begin Halfway end Milbrodale Rd Turn off
12.8 km – about 22 mins
D) Begin Milbrodale Rd end Broke
29.5 km – about 22 mins
E) Begin Broke end Wollombi (coffee/food)
42.5 km – about 32 mins
F) Begin Wollombi end Kulurna (gas for Testas)
25.4 km – about 20 mins
G) Begin Kulurna end Pacific Highway
Ignore G to H, Google maps wont let you turn right from peats ridge road onto Pacific Hwy without doing some loopy thing
6.3 km – about 4 mins
I) Begin Pacific Highway end Roadwarriors (coffee)
24.0 km – about 25 mins
J) Begin Pacific Highway end Berowra turn off.
Like I said, maybe a little long but definitely worth a shot at some stage. I've done it twice in the past two weeks and I'm seriously considering going back for more this weekend!
