In September 2018, four of us did a self-guided tour of the Cabot Trail on Cape Breton Island, the northeast tip of Nova Scotia. Instead of contracting with a tour company, we rented a van and took turns driving it. We biked most of the trail, including the out-and-back to Meat Cove, in five days of riding. My route for the week was 194 mi (my route is what's shown in the picture below), but because we traded off driving, the distance biked varied by person.
