Due to the impressive canopy provided by the redwoods, runners enjoy cool conditions ideal for distance running, although GPS devices may occasionally lose signal under such dense cover.

Beyond the challenge and natural wonder, every runner completing the race is awarded a medal, celebrating their achievement in this dazzling intersection of athletic rigor and natural beauty. This marathon is more than a race; it is an immersive running experience that combines the thrill of the sport with Northern California's majestic redwood scenery, offering both seasoned marathoners and amateur runners a course of unmatched beauty and opportunity.

Expect temperatures between 46-68°F (8-20°C) with moderate humidity during the Humboldt Redwoods Marathon in mid-October. Morning fog often dissipates by noon, leaving behind light winds and occasional rain showers. The shaded course beneath towering redwoods ensures a cooler, sun-protected run.

The Humboldt Redwoods Marathon offers runners a breathtaking journey through the ancient redwood giants of Northern California. This double out-and-back course unfolds entirely on paved roads, weaving through the serene beauty of Humboldt Redwoods State Park.

Runners will experience a total elevation gain and loss of about 1,200 feet, featuring a steady 200-foot climb over the first 6.5 miles and smaller rolling hills, mainly around overpasses. The race begins and ends near the iconic Dyerville Bridge, with the entire route set along the scenic Avenue of the Giants.

One of the course's most captivating features is its almost continuous canopy of towering redwoods, providing cool, shaded conditions—though these majestic trees can occasionally interfere with GPS signals. Thirteen well-stocked aid stations dot the course, offering refreshments like Gatorade, fruit, and energy gels to keep runners fueled.
