​The BT 700 isn't the only multi-day bikepacking route in Ontario. The Central Ontario Loop Trail (COLT) links a number of small communities in the Kawartha Lakes region of Ontario using mostly rail trail and some great stretches of gravel road. The map above shows the route I followed in 2017.
You can find more details about the route from my post on Bikepack Canada: https://www.bikepack.ca/colt-bikepack
My route is Inspired by Miles Arbour's original Central Ontario Loop Trail (COLT) route on BIKEPACKING.com. For more information on how the COLT name came to be, and the history of the route, view another version of the COLT here:  http://www.bikepacking.com/routes/central-ontario-loop-trail/
Note that Miles in the Bikepacking.com route ventured further south to ride along the lakeshore, but we decided to stick with the quieter inland option.
