Avenue of the Giants Marathon

Registration is open via RunSignup with tiered pricing that increases as the date approaches. The race typically sells out, and the 2026 edition sold out entirely with a waitlist. Sign up early to lock in the lower price and guarantee your spot.

Yes, the course is USATF certified and qualifies for Boston. That said, only a small share of finishers hit the BQ standard each year, so go in knowing it requires solid execution even on this flat course.

The course is nearly flat with a net elevation change of just 6 feet. Total gain across the full marathon is under 700 feet, spread across gentle rolling undulations rather than distinct climbs. There are no significant hills to account for in your pacing.

The time limit is 6 hours.

Early May conditions typically run cold in the morning and cool through the afternoon, with the possibility of rain and high humidity under the redwood canopy. Bring a throwaway layer for the start and be prepared for damp conditions even if it stays dry.

The recent finisher count is around 400 runners, making this a small, low-key event. The intimate atmosphere is part of the appeal, but it also means the race sells out, so registration timing matters.

The race is in Weott, in rural Northern California near Humboldt Redwoods State Park. The nearest airport is Eureka/Arcata (ACV), about 60 miles north. Driving from San Francisco or Sacramento takes roughly 5 hours. Rental car availability in the area is limited, so book transportation and lodging well in advance.
