2027 Moonlight Beach Half Marathon, 10k & 6k

The Moonlight Beach Half Marathon, 10k & 6k is a St. Patrick's Day-themed Shamrock Run held at Moonlight State Beach in Encinitas, California. Participants can select the half marathon, 10k, or 6k. All three races commence and conclude near the beach, west of I-5 by Encinitas Boulevard. The half marathon course is set against a Pacific Ocean backdrop, starting from Encinitas Boulevard with Moonlight State Beach serving as the event's home base. This is the third year for the event, which embraces the holiday spirit through green attire and Irish-themed race-day atmosphere, rather than aiming to be a long-established classic.
