Welcome to the information page for the ONU Polar Bear Indoor Marathon and Half Marathon at Ohio Northern University's Sports Center in Ada, Ohio. We are excited to be able to host this event, which benefits the ONU cross country and track & field teams.

The course will be 211 laps (105.5 for the half marathon) on the indoor, 200-meter track in the field house in the ONU Sports Center. Every 30 minutes, runners will change directions after finishing their current lap. While you may be able to watch the snow falling through the glass walls, the conditions for the race will be comfortable and dry.

The marathon course is USATF certified: OH10061PR. Please note that certification indicates that the course is not shorter than the marathon length. However, as is the case with any track event (or road course with numerous turns), runners will likely run a further distance as they pass competitors on turns and as they switch directions in outside lanes. Thus, many runners find that running a ‘personal best’ marathon time in an indoor marathon is not as easy as the ideal weather conditions and flat terrain might suggest.
