The Hard Corps Race Series offers numerous competitive races and family fitness events throughout the year explicitly for Camp Pendleton Active Duty, their Dependents, Retirees, and other authorized base patrons. Many family events are free and all races are extremely affordable as they are offered with a minimal registration fee. Events include Dog Walks, Trail Runs, multiple Holiday Themed Walks and Runs, water sports, and a virtual run celebrating the Marine Corps Birthday.

Each event also offers the opportunity for Marines and Sailors to volunteer and raise money for their Unit and Family Readiness Funds and receive a Letter of Appreciation.
