An out-and-back along Grand Traverse Bay
The route follows Birchwood Drive, East Shore Road, Center Road and Bluff Road after an opening residential section. On the return, runners approach the starting area before completing the final stadium section. Study the full map so that reaching the original start does not feel like an unexpected extra finish segment.
The half marathon starts near the full marathon’s turnaround, making its transport arrangements different. Do not board a half-marathon bus or follow its start directions merely because both distances finish together. Confirm the 2027 full-marathon parking and walking access before settling on a race-morning plan.
The organizer describes a flat, largely shaded paved course, but the detailed page still says the 2026 full marathon began at 07:15. Its displayed price tiers, finish closure and Center Road reopening also need a 2027 check. The newly confirmed race date does not automatically update every older operational field.
The full course prohibits pets, baby joggers and other wheeled vehicles, and strongly discourages headphones. Review the final policy and current forecast before choosing equipment. Registration capacity is limited and opening is scheduled for December 1; a previous-edition waiting-list label does not establish current 2027 availability or a guaranteed place.
