2026 Avenue of the Giants Marathon

The Avenue of the Giants Marathon takes place in Humboldt Redwoods State Park, located in rural Northern California. This event features a selection of distances:

  • Marathon
  • 1/2 Marathon
  • 10k

The course is set on a paved road that winds through old-growth redwood trees and follows a natural creek. While the route includes gentle uphill sections, it is described as mostly flat. The marathon distance is a certified course and serves as a Boston Qualifying event.

The event is staged at the Dyerville Bridge Overlook. The race is organized by the same running club that produces the Humboldt Redwoods Marathon, which utilizes the same course during the fall season. Registration for the 2026 edition is currently restricted to a waiting list as the initial spots have been filled. Visit the organization's website for the most recent information.
