Eden Autism 5K & Fun Run/Walk 2026

The Eden Autism 5K & Fun Run/Walk takes place annually in October at 2 Merwick Road in Princeton, New Jersey. It offers a USATF-certified 5K for runners and a 1-mile Fun Run/Walk for walkers, families, and younger children, both beginning at the same morning hour. Registration fees are reduced for ages 5 to 17 and USATF members; children 4 and under participate for free. Same-day registration is available for those deciding to join on the morning of the event. The event benefits Eden Autism, an organization that assists individuals with autism from diagnosis through adulthood. The first 1,000 participants will receive a long-sleeved shirt, hat, and finisher medal. Awards for the 5K include prizes for the top overall female, male, and non-binary finishers, as well as the top three runners in 10-year age categories ranging from 9 and under to over 80. A race festival precedes, accompanies, and follows the races, featuring face painting, balloon animals, and craft tables.
