Catalina Island Half-Marathon & 10K

This spring, racing fans and runners of all skill levels and ages will have the opportunity to “run the course” at the 8th Annual Grand Prix Foundation of Long Beach 5K on April 12, 2026, which will benefit local charities through the Grand Prix Foundation of Long Beach.

Participants will run a two-lap tour of the world-famous Acura Grand Prix of Long Beach racecourse including Pine Avenue and Seaside Way, with the finish at the official Grand Prix start/finish line on Shoreline Drive. Kids 12 and under can get in on the action with the Kids’ Turbo 1K, which will take place after the main races on a portion of the regular racecourse. The other two races will be the Elite/Pro 5K (those who can finish the race in under 25 minutes) which will start at 7:00 a.m. and the run for the general public, beginning at 7:30 a.m.

Each runner will receive a finisher medal, an official Grand Prix Foundation 5K t-shirt, post-race refreshments and two complimentary Friday general admission tickets to the Acura Grand Prix of Long Beach, a $68 value. There will also be photo ops and activities in the 5K festival area at the conclusion of the run.
