The Detroit Free Press Marathon returns this weekend, October 16-18, 2026, hosting 50,000 runners across eight distinct race events. The course uniquely traverses international borders, including an underwater segment through the Detroit-Windsor Tunnel.
Why it matters
This long-standing event is Michigan's largest road race, drawing a massive field of participants to the city for a multi-day fitness celebration. Its historic international route provides a singular logistical experience for distance runners in the region.
This annual event, which began in 1978, expects 50,000 participants across eight races versus historical averages. It remains unclear how many of these runners will complete the full marathon distance versus the shorter sub-events.
