Jim and I took a five day loop hike a couple weeks ago, roughly 100 miles.

Link to Google Map (gmap-pedometer) allowing you to zoom in on details of the route, satellite images, etc. The line follows our route, within a few hundred meters. (If you double click in gmap it will extend the route, which will make you quite confused.)
Home to San Francisco via CalTrain.
San Francisco to Marin county along the waterfront and Golden Gate Bridge.
Big loop through Marin County.
Return to SF via Sausalito Ferry.
Hiking through settled areas does not compare to wilderness hiking, but it is delightful in its own right. We have now taken 6 walks (3-5 weeks each) through settled areas in the UK and France, and 6 walks (3-6 days each) through settled areas in the San Francisco Bay Area.
We still do a lot of backpacking in roadless areas, near home in the Bay Area (Coe, Big Sur, etc), in the Sierra, and in Utah. But we've added multi-day walks through settled areas to our repertoire.
On the walks through settled areas, we usually have access to grocery stores and/or restaurants every day or two. On the Marin County part of this walk, we passed two restaurants (ate at both), but did not pass by any grocery stores.
Backpacking without air or car travel is good for the soul, as well as the planet. We appreciate our good fortune to live in the San Francisco Bay Area where there is so much backpacking available via public transit. (http://www.transitandtrails.org/)
MAKING IT LONGER???
Here's a loop at Pt Reyes that could be combined with parts of this trip, to make a mighty fine 10-12 day walk (at ~20 miles per day).
