About the race
Vallejo, California hosts the Mare Island Half Marathon, 10K and 5K, a scenic, historic race on Mare Island. The course stays entirely on the island, pairing waterfront views with naval history and a post-race celebration at Mare Island Brewing Co. Distances include a Half Marathon that climbs to the island’s high point for sweeping views of San Pablo Bay and the Bay Area peaks, plus paved and unpaved sections; a 10K along the San Pablo Bay Trail and through Admiral housing; and a 5K by the Old Admiral housing—quick, beginner-friendly, and stroller-friendly.
A kid’s 0.5K dash adds family fun. All participants receive a race t-shirt and finisher medal, with age-group awards. Visit the organization's website for the most recent information.
