About the Detroit Free Press Marathon
Detroit's fall marathon is defined by its U.S.-Canada route, border-crossing logistics, and full race weekend that draws both goal-time runners and destination racers.
Course
The marathon starts in Detroit, crosses into Canada by bridge, returns through the tunnel, and finishes after city neighborhood miles. A valid travel document is part of the race plan.
Race-day weather
Mid-October in Detroit can be cool and quick, with wind more important than heat. Runners should expect temperature swings between the start and later downtown miles.
