I ride through a bit of Blackheath common and then down through Greenwich park on the first leg of my commute. A Dedicated bike path, which you could really hammer down without the fear of pedestrians or cars would be good through greenwich park. On Blackheath it would be great if there was a bike lane which was cut off from the road (a curb type thing) as the road is quite narrow and the cars tend to block the way, which is really annoying as it would be a fast section otherwise. There ya go, thats my piece!
