2027 Avenue of the Giants Marathon
The 2027 Avenue of the Giants Marathon is a small, remote, scenery-first marathon held on May 2, 2027, in Humboldt Redwoods State Park. The course is a double out-and-back on paved park roads beneath 300-foot old-growth redwoods, mostly flat to gently rolling with about 211m of elevation gain. It is a USATF-certified Boston qualifier with a 6-hour time limit.
In early May, the redwoods are lush and the coastal air is cool, making this a perfect time to run beneath the towering ancient canopy of Humboldt Redwoods State Park. After your race, wander the nearby Avenue of the Giants to spot elk, and warm up with a local craft beer and fresh oysters in the surrounding towns.
Event Details
211m
The course runs entirely on paved park roads through the heart of Humboldt Redwoods State Park, threading beneath 300-foot old-growth coast redwoods the entire way. The redwood canopy shades nearly the whole route and the cool, humid coastal air keeps overheating at bay. It is described as cathedral-like old-growth forest, with no city or big crowd.
