  • Volunteer Information:

    Course Monitoring and Traffic Control

    • We need a lot of people out on the course during the race to make sure runners and drivers know where to go. Volunteers will help deploy traffic signs and barricades to close and reopen roads.

    Start and finish areas

    • We expect a good crowd at the Arcata Plaza (half marathon start) and at the C Street Plaza in Eureka (finish line for all races). Volunteers will help with food tables, parking information and more.

    Pre- and Post-race setup and tear down

    • We have plenty of work for volunteers in the days leading up to the race, and we also need a crew of volunteers to help pick up and put away everything after the race.
