Detroit Marathon Pace Calculator & Race Plan

Detroit is unique because you cross into Canada via the Ambassador Bridge and return through the Windsor Tunnel. The bridge climb at mile 3 is the biggest elevation feature. Otherwise it's a relatively flat course through the city.

October weather in Detroit is usually good for running. The model accounts for the bridge climb and the typical conditions.
