Detroit Free Press Marathon pacing strategy

The course is flat for long stretches, but the climb onto the Ambassador Bridge in the first miles is the biggest hill. Run it by effort and do not chase pace there. Cold starts are common, so keep warm and settle into an even pace after the bridge.

Pacing by course section
Section	Terrain	Advice
mile 1–8	Fort Street, Ambassador Bridge at mile 2, Windsor, then the tunnel at mile 8	Start easy; the tunnel has no aid station.
mile 9–18	Downtown Detroit and city neighbourhoods	Settle at goal pace.
mile 18–26.2	Dequindre Cut, Rivertown and the run to Campus Martius	Hold form and push in the final miles.

Fueling notes

RunnersConnect notes the tunnel at mile 8 has no aid station, so plan to drink before it. Take a gel before you enter the tunnel.

Race-day tips

Bring a passport or enhanced driver's license for the border crossing
