About
The NorthShore Inline Marathon is the nation’s largest point-to-point inline marathon, offering full marathon, half marathon, and tunnel 10k races along Lake Superior with professional prize money and a premier inline skating event.
Catering & aid stations
Aid stations (Verpflegung) are located along the course and at the finish, offering food and drinks. Not a pacemaker service.
Pacers
Pacemakers will be present for the marathon and half marathon to help participants hit target times per wave; flags will identify pacers on course. For the Tunnel 10k, pacing is self-driven with traffic control in place.
