The Avenue of the Giants is one of the most beautiful races in the world! It runs through old growth redwoods and follows a natural creek in the middle of a state park. Staged on "The Avenue of the Giants" in Humboldt Redwoods State Park, located in rural Northern California. Course is on a paved road that winds gently up hill but is mostly a flat, fast destination race. With little to distract you, the tall trees inspire the athlete in each of us to be strong. The course is certified and the marathon is a Boston Qualifying event.
