We’ll forgive you if you have trouble concentrating on the road ahead of you while running The Humboldt Redwoods. After all, you’ll probably be looking up at the old growth redwood trees which tower over the course. Course is on a paved road the 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. Source
