The event expects 15,000 runners, offering sponsors direct access to a motivated, brand-loyal audience before, during, and after the race. The field splits almost evenly between men and women, skewing toward wellness-focused, fitness-driven adults who plan their training and travel around race day, generating an estimated 100,000+ social impressions around the event. Sponsorship blends digital promotion, on-site branding, and experiential engagement, letting partners showcase products and messaging in a trusted, energetic environment. Proceeds support local youth running and sports programs, giving brands a cause-driven angle alongside the visibility.
