    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...”
