Granite Bay 5K & 10K

New Name, New Trails, Same Community Heart: Welcome to the Granite Bay 5K!The tradition you love is back—but with a fresh look and more ways to move! This year, we are thrilled to officially rebrand our annual event as the Granite Bay 5K. While our name has changed, our mission to support the Eureka Union School District remains the heartbeat of every step we take. Join us for an electric morning of fitness and fun on Sunday, September 13th, 2026! With over 1,000 participants cheering and running together, this is Granite Bay’s premier community event. Whether you're chasing a personal best in the 10K, enjoying a scenic stroll with the family in the 5K, or cheering on the little ones in the ¼-Mile Kids Race, every single step you take directly supports the Eureka Schools Foundation (ESF).
