How about a ride sometime next w/e (Mar 20/21)?
One of my favourite rides is up to Mitchell Park. See http://www.bikely.com/maps/bike-path/Vineyard-Mitchell-loop.
This ride starts at Vineyard Railway station (on Richmond Line) and is just over 30km in length. It does contain several kms of gravel road though - Is that ok? Happy to do other rides starting at Rooty Hill or Penrith. There are other people like Angela who live locally....might see if they wish to join in.
