Humboldt Bay Marathon, Half Marathon, and Marina Mile

The Annual Humboldt Bay Marathon will be in Sunday. The Humboldt Bay Area combines spectacular scenery with the perfect climate for year round running. August is a dry month with an average high temperature of only 62.6 degrees (17 Celsius), so ideal conditions for this race are almost guaranteed.

Whether you are trying for a Boston qualifying time, striving for another personal record, or just looking for a uniquely beautiful place to run, the Humboldt Bay Marathon is exactly what you’re looking for!

For years, Humboldt runners have been running on the scenic roads and trails surrounding Humboldt Bay. Many of these runners have done a 20+ mile lap around Humboldt Bay as part of their training for marathon races. In the summer of 2014, the thought occurred to us to organize a marathon that would circle Humboldt Bay. We are very excited to be turning this concept into reality!

Humboldt Bay Marathon is a nonprofit affiliate of the Road Runners Club of America. Our mission is to promote fitness, outdoor recreation and trail projects in the Humboldt Bay area.
