Bottom of Cooper Union...you can either cross the road and hit the short single track to the right or make a right on Sterling Mine Rd and then left on Long Meadow. Either way you want to get to Long Meadow, right onto Eagle Valley, stay right, then left on South Gate through the golf course.
Basically the answer to your question is yes, it's mostly road. Memory says it feels a bit uphill overall towards Sterling and a bit downhill back towards Ringwood, but that's my memory. Roads are really quiet after Sterling Mine; it's a nice cruise.
