The marathon starts on Yonge Street north of Gerrard and finishes on Bay Street just north of Queen. In between it passes through the downtown core, runs along the waterfront and takes in more than a dozen neighbourhoods. Aid stations come about every 3 km, and you are placed in a start corral by expected finish time. The time limit is six hours and the field is capped, so enter early. Race Central is at Nathan Phillips Square, where bag check is located.
