Endless Summer in the LBC 10K
Race Day Weather
Warm start, high humidity
Starting at 67°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Light winds shouldn't be a major factor for pacing. High humidity (81%) will make it harder to cool down through sweat — increase fluid intake accordingly.

Race Info
The 10K starts and finishes at 5400 E Ocean Blvd on the Long Beach beachfront, on a flat course along the beach path with ocean views for its full length, using the same official 5K/10K course map, distinct from the half marathon's route. The course runs through public beach paths and parks that remain open to the public during the race, so runners share the path with pedestrians.
