Mackinac Island, MI
Entry is $60 now and rises to $65 after Jul 31, 2026, so registering before then saves $5.
The course runs the interior trails and shoreline of Mackinac Island, so you get woods and water in the same race. Fall color is usually near its peak, and the island is quiet by then, with the summer crowds gone. Trails here tend to roll rather than climb hard, but the ground is natural surface throughout.

The Mackinac Island Great Turtle Half Marathon & 5.7 Mile has been held every year since at least 2024. That is as far back as RunSignup's records for this race go, so it may well be older.

Almost certainly not. Half the 5.7 Miles field finished slower than 1:07:40, and the last recorded finisher came in around 2:34:30, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.
With 824 finishers there are runners at every pace, so you are never out on your own. There is no qualifying time, and the finish-time spread above shows how varied the field really is. If it is your first 5.7 Miles, that spread matters more than the winner's time.
The 5.7 Miles winner ran 29:46 while the median finisher took 1:07:40. That spread points to a broad, mostly recreational field rather than a race dominated by club runners.
