Online registration closes on Wednesday, September 16, 2026, by midnight, but day-of-race sign-ups are available from 7:00 am to 8:00 am in Heritage Hill Park. Participants who register early will receive a custom event T-shirt during packet pick-up at the Heritage Hill Airpark on Friday, September 18, 2026, between noon and 6 pm. Race day excitement begins with pre-race preparations at Heritage Hill Park from 7:00 am to 8:00 am.
