Mackinac Bridge Walk in St. Ignace
The Mackinac Bridge Walk is an annual Labor Day tradition in which participants walk roughly five miles across the Mackinac Bridge, connecting Michigan's Upper and Lower Peninsulas. Held since the bridge's 1958 dedication year, walkers are typically bused from Mackinaw City to St. Ignace to begin, and Michigan's governor has participated nearly every year, with turnout historically reaching tens of thousands.
Its iconic bridge route and mass participation make it a strong sports/adventure row.
