This is an interactive map of the bike course. I didn't realize they have to do the loop to Orleans and down Colonel By three times, but then again they do have to ride 180 km and multiple loops is easier for race directors to manage and also great for families and friends cheerleading: https://www.ironman.com/races/im-canada-ottawa/course#bike

And here is the interactive run course:
