Vancouver Marathon
It is certified by both the International Association of Athletics Federations & Association of International Marathons and Distance Races as a qualifying marathon race. It started in 1972 after a small group of 46 runners ran five loops of Stanley Park to finish the first Vancouver International Marathon (which was known as Lions Gate Road Runners International Marathon). A Full Marathon is a Boston Marathon qualifying event and is 42 km, and a Half Marathon is 21 km.
