The Harborthon 5K’s starting line is located on Camp Harbor View grounds, overlooking views of the Boston's city skyline and Harbor. Runners will proceed past several of the camp’s facilities and onto Moon Island Road. The course then shifts inland on to a paved road, surrounded by greenery. Runners will reverse route as they approach the Long Island Bridge, continuing on the same path back to the camp grounds, past an old war bunker and across the finish line near the CHV ropes course. With paved roads and water stations throughout, this certified course is an enjoyable, scenic, and one-of-a-kind 5K experience.
