Great Turtle Trail Run

The Great Turtle Trail Run is a scenic running event held annually on Mackinac Island, Michigan, typically during the last open weekend of the season in late October. The event features a challenging half marathon (13.1 miles) and a 5.7-mile run and walk, both courses showcasing the island’s beautiful shoreline, interior trails, and landmarks like Arch Rock. The half marathon starts and finishes near Mission Point Resort, with a mix of paved roads, gravel, and bike trails. Participants enjoy a commemorative garment, a unique finish medal, free digital photos, post-race refreshments, and a friendly atmosphere. The race is part of the Mackinac Island Trio Series, encouraging runners to complete multiple island races. Visit the organization's website for the most recent information.
