Carlsbad 5000

Carlsbad 5000 is a landmark oceanfront road race in Carlsbad, California, USA, widely known as the “World’s Fastest 5K.” Organized by Groundwork Endurance, LLC, the event is built around a full day of separate 5K races rather than a single all-comers start, giving it a distinctive mix of elite performance, age-group competition, and festival energy. Set in Carlsbad Village along Coast Highway 101, the course is flat, fast, and highly spectator-friendly, with runners racing by the Pacific before finishing beneath the iconic Carlsbad sign.
