In 2017 I did this bike tour of Southeastern Quebec with five friends. We biked 253 miles in six days with one day of rest in the middle, when we stayed in the city of Trois-Rivières for two nights. A few of us went kayaking that day.
This map gives you everything you need to duplicate our Quebec Bike Adventure. Also attached here is the route sheet that I created to go along with the map.

If you’d like to shorten the loop a little bit and simplify the logistics, you can skip crossing the river over to Trois-Rivières (which requires a shuttle that is explained in detail in the route sheet) and instead spend a night or two in Bécancour or elsewhere. By doing this you miss out on the cool city of Trois-Rivières, but you also eliminate the need to take the bike shuttle across the Pont LaViolette.
Here are some other helpful sites that go with this map:
Quebec Tourism Info by Region — The two regions you are in for most of this bike tour loop are Montérégie and Centre-du-Quebec and you skirt Eastern Townships and Chaudière-Appalaches. If you cross the St. Lawrence river over to Trois-Rivières you will be in Mauricie and if you bike towards Montreal on the north side of the river you’ll be in Lanaudière. There’s plenty of info on this website, but you can click through to go to websites for each region (where you can request that they mail you even more info, including cycling-specfic maps).
