Moonlight Beach Half Marathon

The Moonlight Beach Half Marathon, now in its fourth edition, has grown to attract ~850 runners from 29 states, with about 8% returning each year. Held on March 15, 2026, the race kicks off from Moonlight State Beach in Encinitas, CA, with a festive St. Patrick’s Day atmosphere that pairs perfectly with the seaside setting.

The course, flat as a pancake with zero elevation gain, runs along the Pacific coast—a straight shot out and back, likely hugging the shoreline. Runners enjoy cool temps (50-61°F) and ocean breezes, making it an ideal PR candidate. The out-and-back route offers continuous ocean views, with the beach and surf providing a constant, calming backdrop.

After crossing the finish line on the sand, participants are treated to a post-race party befitting the holiday—think green-themed refreshments and live music. With its growing field, scenic coastal route, and beginner-friendly flat profile, this half marathon has become a favorite for locals and destination runners alike, offering a relaxed yet spirited race-day experience.
