With new marathons in Canada popping up while others fold, it’s difficult to keep track of the options in each province. Two weeks ago, Canadian Running posted a story of all the Quebec marathons for 2017. Next up is Ontario.

There are currently 28 marathons in Ontario, plus one that begins in the United States and crosses into Canada. That’s four more than in 2013 though there have been marathons that have been discontinued, Thunder Bay Miles With the Giant for example, while others have been added to the calendar.

Some of the marathons share the same date, so you couldn’t run them all in a year, but you could theoretically run many of them.
