The signature run in Windsor is the riverfront path on the the south bank of the Detroit River. It runs for 5 km between the Ambassador Bridge and the Joan and Cliff Hatch Wildflower Garden to the east, passing the Windsor-Detroit Tunnel at the 3 km mark. In addition to a great view of the Detroit skyline across the river, there are parks and sites along the whole way. From west to east — Windsor Sculpture Park, Steamboat Wharf, Dieppe Gardens (commemorating D-Day), Festival Plaza, and Great Western Park. A nice 1 km add-on is to run on the path south through the International Gardens, accessed in Centennial Park.
Longer Run: Continue east of the Wildflower Garden for another 3.5 km to the Peace Fountain in Coventry Gardens. There are a couple sections along Riverside Dr. where there aren’t water views, but there are nice paths through Alexander Park, Goose Bay Park, and Reaume Park.
There’s also a centrally located running store, The Running Factory, about 2.5 miles east of the eastern terminus of the Riverfront Trail.
Note: If coming from Detroit, a passport is needed to get into Canada and there can be queues at the border. It is not possible to walk across the Ambassador Bridge.
