I just did my first bicycle commute from my new location. The old one was from the Melbourne suburb of Ringwood North, and was about 26.5km with 225m climbing, while the new, from Montmorency is 24.9km with 400m climbing. There's some major hills in the early part of my new ride to work, with grades of 10-15%, but overall the route is easy enough, particularly since I ride it between 5 and 6am when there's not much traffic.
Montmorency (named after an old farm, which itself was named after Montmorency just north of Paris) is nice, but aïe, c'est très vallonné!
