Coming September 20, 2015. Aloha! Get a bit of the island spirit with the Island Girl Half Marathon, Relay and 5K race. Held on Toronto Island, the largest, outermost island of the Toronto Islands, a chain of small islands accessed by ferry from the city of Toronto, the most populous city in Canada. The route will be an out and back loop on a flat, paved road, free of cars. At the finish line, you’ll be greeted with steel drum music, grass skirts and tropical fruit. An island celebration!
