We have created Humboldt Bay Marathon as an organization dedicated to promoting and supporting trails and outdoor recreation in Humboldt County. We graciously ask that you be supportive and patient with the impact on traffic. Thank you!
For questions, please contact Rich Baker: firstname.lastname@example.org
The safety of our runners and our volunteers is our first priority. The main roads used for our courses will either be fully closed or have one side of the road closed.
Cross traffic will be allowed at some intersections, but these will be heavily controlled with barriers and flag people to ensure that runners have priority with no interference from crossing traffic.
The time limit for the marathon will be 6 hours and 30 minutes. The half marathon course limit is 4 hours and 30 minutes. Roads will be reopened, and runners who fall behind this minimum pace will be required to stop and abandon the race.
