DRIVING DIRECTIONS: Google Maps Link to Ferry Dock

CANCELLATIONS: Registrations are non-refundable and non-transferable.

HEADPHONES POLICY: Since parts of this race include very narrow trails with steep drop-offs along the course, it is imperative that runners can hear each other in order to pass safely, even if they are running at a slow speed. For safety reasons (and for the enjoyment of your fellow runners) headphones (and any other audio devices) are NOT allowed.
