The new USATF Certified marathon course for 2025 is almost entirely on the Eureka Waterfront Trail and the Humboldt Bay Trail with a loop around Klopp Lake in the Arcata Marsh!  The half marathon will start in Eureka and head north towards Arcata on the Humboldt Bay Trail and then turn around and return to Eureka.  The 5K race will be on the Eureka Waterfront Trail.

There will be plenty of friendly and helpful course monitors. Aid stations will be approximately every 2 miles. Here is the course map for all races.

    Сustom artwork on all of our medals and shirts

    We have commissioned local artist (and runner!) Sara Starr to do the artwork for our shirts and medals. Read more...

    “The art symbolizes several things I love about Humboldt Bay. I have run or biked many parts of this marathon route, including the windy road from Sunnybrae to Freshwater, the redwood forest paths and hills of Arcata Community Forest, the Samoa Bridge, and the streets of Old Town Eureka...”
