Using the metro to keep in shape

Interesting idea to use the metro to keep in shape.

I’d been pondering working out a walking path indoors, given that sidewalks have been slabs of ice for days. If I recall correctly, you can start at Place des Arts, walk south to the Palais des congrès, westward to Place Bonaventure and then northward through Place Ville-Marie into the Eaton Centre or Place Montreal Trust, all without going outside – is that still true?
