The underpass where Bull Creek Flats Road meets Hwy 101 and the Avenue of the Giants
The Avenue of the Giants Marathon is one of the most scenic courses in the country. Staged on 'The Avenue of the Giants' in Humboldt Redwoods State Park, located in rural Northern California, the paved course winds through giant old growth redwoods.
The marathon course is a double out and back of the half marathon course which is entirely on paved roads.
Heading south along the Avenue of the Giants (Highway 254), all the way along six and a half miles of paved roads to the turnaround point near Hammond Grove and Truss Creek, where runners then make the turn and retrace their steps back toward the start.
All along the course, which starts out flat for roughly the first mile and then becomes hillier and more challenging as runners move into the middle miles of the race, the scenery changes from a mix of redwoods to wide open spaces.
There, you can get a glimpse of the majesty of the surrounding mountains, and back again to canopies of redwoods overhead. Organizers say that even in the non-shaded portions of the course, the elevation and the season of year combine to provide cool temperatures in most years along the entire race course.
Runners will encounter three aid stations along the course and should expect a course that climbs gradually but steadily over the first half of the race, and then descends slowly and steadily along the last part of the race to the finish line at the Dyersville Bridge.
