Already registered for the race through the Marine Corps Marathon 10K registration page? We'd still love to have you on the OAR team! Before you hit the pavement decked out in your Halloween costume and ready to trick-or-treat this October 31, hit the pavement with the RUN FOR AUTISM-Marine Corps Marathon 10K team. All OAR runners receive a custom race shirt and t-shirt, training and fundraising guide, personal fundraising webpage, invitation to the Runner’s Recognition Dinner, and staff support.
