There are so many wonderful trail running opportunities in Eastern Ontario! The following is a list of some of my favourites. There are many other great trails to run too that I have not listed, however please always respect the wishes of property owners when trail running and only go on approved trails, or ask for permission.
The Ontario Trails Council includes a number of these trails in addition to others.
Adirondacks (NY) – The Adirondacks are a short drive from Eastern Ontario and offers the most easily accessible mountains within driving distance in this area. Here is a great interactive map to plan your route.
Algonquin Provincial Park – Another playground offering from Ontario Parks with unlimited trails for runners looking for anything from short runs to ultra distance. Enjoy!
Batawa Ski Hill (Trenton) – Trail system north of Trenton that is used for the Fat Ass Trail Race.
Bon Echo Provincial Park (Cloyne) – Assorted trail network of some fairly technical single track trails. Day/annual pass required.
