The Detroit Free Press Marathon is the largest participatory event in Michigan and North America's largest international race, run each October since its founding. The course crosses into Canada via the Ambassador Bridge, giving runners the rare chance to become international athletes in a single race, with 26,000-plus runners and 100,000 spectators on hand. Race weekend draws families, health-focused adults, and young professionals citywide, plus 50,000-plus at the Health and Fitness Expo. Total event reach tops 186,000, with a 30,300-strong social following and multi-channel exposure through Detroit Free Press and its parent, Gannett/USA Today Network. Sponsors reach a health, community, and international-prestige audience across digital, print, and broadcast, from Campus Martius festivities to the Kid's Marathon and Detroit Public Schools programs. It's a platform built for brands seeking scale with civic credibility.
