Race details
- Marathon : 211 laps on the indoor 200-meter track (USATF certified OH10061PR)
- Half Marathon : 105.5 laps on the same indoor 200-meter track
The course is run entirely on the indoor field house track. Runners change directions at regular intervals; when the direction change occurs, participants move to the outside lanes until all have switched. Timing will be recorded with a gun start and a FinishLynx system, with lap splits tracked and provided after the event. There are two aid stations on the track (one at each end); water and sports drinks will be available and runners may place personal supplies on track-side tables. Headsets are not allowed; music will be played. Spectator seating is available beside the track. Only the first male and female finisher in each distance receive awards; there are no age-group awards. The indoor marathon time cannot be used to qualify for the Boston Marathon.
