Ocean Running Club's Seaside Half Marathon and 5K 2026

The Ocean Running Club hosts its Seaside Half Marathon and 5K on the central New Jersey shore in Seaside Heights. The course is fast and flat, utilizing the boardwalk, beach, and Atlantic Ocean views. The event takes place in October, with average local temperatures ranging from the 40s to the upper 60s. Participants can choose from three options: the Seaside 5K, the Seaside Half Marathon, or the Seaside Challenge, which involves running both races consecutively. The half marathon follows an out-and-back route on the boardwalk and paved city streets through Seaside Park, extending towards Island Beach State Park. Both walkers and runners are welcome. Its flat terrain is ideal for those training for fall marathons in the New York and New Jersey areas. Over 400 participants finished a recent edition of the race, which has a history spanning nearly fifty years. The 5K begins before the half marathon, Challenge runners receive three medals, and proceeds benefit the Tri-Boro First Aid Squad and the Ocean Running Club Scholarship Fund.
