The health order from the Los Angeles County Department of Public Health requires all race participants and attendees to be fully vaccinated for the coronavirus or obtain a negative COVID-19 test result prior to attending the event.

All participants must present proof of vaccination or a negative COVID-19 test result before being allowed to pick up their race bib.

Physical infrastructure remaining from the last month’s Acura Grand Prix of Long Beach has prompted an earlier start to the half-marathon to alleviate the crowd of half-marathon participants at the start of the race. The half-marathon will start in waves beginning at 7 a.m. with the competitive wave.

The waves will continue through 7:50 a.m.

Runners will only be able to access the start line staging area at Marina Green via two pedestrian walkways because of the physical infrastructure remaining from the Acura Grand Prix of Long Beach.

The coronavirus pandemic has prompted organizers to hold the race’s Health & Fitness Expo outdoors.

The Long Beach Marathon was first held in 1982. The race was disbanded in 1996 because of financial problems, then revived in 1999 under new management.
