  We'll forgive you if you have trouble concentrating on the road ahead of you while running The Humboldt Redwoods Marathon, half or 5K.

This race is in Humboldt Redwoods State Park and the Half Marathon follows the second half of the iconic Avenue of the Giants Marathon course.

  All courses are USATF Certified. The Marathon is a Boston qualifier. The race starts and finishes at the Dyerville Bridge.
