Now in its 11th year, the Humboldt Bay Marathon has quietly built one of the most compelling late-season Boston Qualifier résumés on the West Coast. Set in Eureka, California — deep in Humboldt County, about five hours north of San Francisco on scenic Highway 101 — this is the rare race that doubles as a genuine destination experience. The 2026 edition runs the newest version of the course, first introduced in 2025, which incorporates a beautiful new stretch of the Great Redwood Trail. It's the flattest iteration yet: a sea-level course, USATF certified, designed to give runners their best shot at a qualifier time.

The Course: Fast. Flat. Coastal.

The redesigned course hugs sea level through the Humboldt Bay Area, with the addition of the Great Redwood Trail segment adding a stunning natural backdrop that you won't find at any other BQ race in California. Expect cool coastal temperatures — the kind of conditions that make legs feel fresh deep into the second half. No mountain passes. No brutal elevation swings. Just a legitimate shot at your goal time with Northern California redwood country as the scenery.

Course profile: Flat · Sea level · USATF Certified (2025 course). Typical race-day temps: Cool coastal (upper 50s–low 60s°F) — ideal for PR conditions.

BQ Credentials

With a BQ rate of 16.4%, Humboldt Bay Marathon consistently produces qualifiers. The new flat course removes the rolling hills that characterized earlier editions — meaning that BQ rate is likely to climb as the course data matures. If you've been looking for a low-key, high-upside late-summer qualifier away from the crowds, this is it.

The Destination Case

This isn't a race you drive to from across town — it's one you plan a trip around. Humboldt County is one of California's most underrated corners: ancient redwood groves, rugged Pacific coastline, Humboldt Bay itself, and a genuinely unhurried pace of life that makes for a perfect race-cation. Drive up Highway 101 from San Francisco — the five-hour journey through the redwoods is an experience in itself. Stay a few days, explore the Avenue of the Giants, and race on August 9th.

The Art

Each year's race artwork is created by Sara Starr — a local runner and artist from Humboldt County — and features a native Humboldt Bay Area animal. It's the kind of detail that makes a finisher medal feel like something worth keeping. Sara's work reflects the character of the region and the community that makes this race what it is.
