Saint Denis is a former industrial suburb situated 9 km due north of Paris. It’s known for its basilica and football team. Running highlights include routes along the Canal Saint Denis and nearby parks.

Canal Saint Denis: 6.7 km (4.1 miles) one-way. Fairly flat.
The 6.6 km Canal Saint Denis connects the communes of Auberville and Saint Denis to the Canal de l’Ourcq, beginning in the northern reaches of Paris in La Villette Park. Where Canal de l’Ourcq heads east, Canal Saint Denis bears north, followed by cement quays along the entirety of the east bank. Some sections are nicer than others, but the park-like atmosphere of the Saint Denis end is noteworthy. Some parts dedicated path, other parts sidewalk along canal. You’ll pass the 81,000 seat Stade de France. Good transport access. ROUTE MAP.
