The final race in Grande Dunes three-race summer series, the Awesome ‘80s 5K is sure to be totally rad. Don your best decade appropriate costume, break out the neon spandex, or dress as your favorite musician or celebrity from the era as you run along the Intracoastal Waterway. End the exercise with two free beers, live music and an amazing sunset.
