Every finisher receives a medal, 5K finishers included, with free medal engraving, and this year’s medals mark the race’s 15th anniversary. Entries also include a full-color keepsake bib, personalized for runners who register two weeks before the race, along with race swag. Live music plays at the venue, and an informal costume contest picks winners who are notified after the race.
