Avenue of the Giants Marathon

The Avenue of the Giants Marathon, held in Humboldt Redwoods State Park along the Avenue of the Giants in rural Northern California, offers Marathon, Half Marathon, and 10K options. The course is a paved, double out-and-back that winds through ancient 300-foot redwoods alongside a natural creek. It is USATF certified and the marathon is a Boston Qualifier, described as one of the world’s most beautiful races and a fast destination course with a gentle uphill in places but overall flat.

The event emphasizes an eco-friendly, sponsor-free ethos, with finisher medals, age-group awards, and a post-race spaghetti feed. A sister October race also exists on the same course. Visit the organization's website for the most recent information.
