What is the longest route that you know of that you can coast on a bicycle without having to pedal?
For the purposes of this question, I would not count mountain roads that just stay on one mountain and switch back and forth.
The reason I ask this is because when I was in school, I could walk out the front door of my university library, hop on my bike, pedal one or two strokes, then roll past the academic buildings, past the dorms, coast into my neighborhood, down my street and roll up to my front door without having to pedal (ok, maybe one stroke here or there). It was about a mile, but it was a lot of fun. Wasn’t fun pedaling back.
