The Detroit Free Press Marathon is Where Detroit and Windsor Run as One

Every fall, thousands of runners and spectators gather in Detroit for one of the city’s proudest traditions, the Detroit Free Press Marathon. Since its start in 1978, the race has grown into the largest running event in Michigan and one of the most unique marathons in the world. With multiple distances, a lively festival atmosphere, and a course that stretches across international borders, the Free Press Marathon has become a must-do for athletes and a must-see for the community.

What makes the event so special is its blend of world-class competition and hometown spirit. The marathon draws elite runners chasing qualifying times, first-timers reaching for a personal milestone, and everyone in between. Friends and families line the streets to cheer, while local organizations and businesses rally around the event to celebrate Detroit’s resilience and energy. Over the course of race weekend, the city is transformed into a hub of motion, endurance, and pride.

The 2025 Marathon Weekend will take place October 17 to 19. Saturday will kick things off with community events, including a 5K, one-mile fun run, and a Kids Marathon that bring families downtown and give young runners their own chance to shine. On Sunday, all eyes will be on the signature events: the full marathon, the international and Motor City half-marathons, and the marathon relay. These races showcase Detroit at its best, blending urban streets, riverfront views, cheering crowds, and the electric energy that only comes from thousands of people moving with the same goal.

One of the defining features of the marathon is its international flair. Runners cross into Canada via the Ambassador Bridge, take in the sights of Windsor, and then return to Detroit through the Detroit–Windsor Tunnel. That tunnel mile, beneath the Detroit River, is one of the most talked-about segments of the race. While it only lasts a few minutes, the experience of running underwater between two nations adds an unforgettable element that keeps runners coming back year after year.

The magic of the Detroit Free Press Marathon goes far beyond bridges and tunnels. For many participants, it is about the community support that lifts them through every mile. Neighborhoods along the course come alive with music, banners, and cheers. Local volunteers hand out water and encouragement with the same enthusiasm as world-class coaches. And when runners cross the finish line back downtown, they are met with a wave of celebration that makes all the training worth it.

The Free Press Marathon has always been more than a race. It is a tradition that unites two cities, two countries, and countless stories of perseverance. Whether you are a seasoned runner, a first-time participant, or someone who just wants to soak in the atmosphere, Marathon Weekend is one of Detroit’s can’t-miss experiences. For those lucky enough to take part, it is a chance to write your own chapter in a story that spans nations, neighborhoods, and decades of memories.
