Cycling Around Ottawa. Episode 2. a 20 Km Loop Around Downtown
This is not exactly my favourite loop, but it is 20 km long, which is a pretty nice and round number.
There is not much else to say, most of the loop is on multi-user paths, except for the bit between uOttawa and Rideau River, but that is a nice, straight, quite street with a painted bike lane.
Nice, although paint is not infrastructure!
