New England Ninja Association (NENA) Indoor OCR Series is a league run series of events geared towards the OCR community's off-season training/ conditioning. Each competition is based off two (2) events, a timed workout and a timed short course race.

The Workout Event consists of 10-15 workout stations that are timed. There can be variations for females and males decided by the gym.

The Short Course Event is made up of 8-15 OCR based obstacles with cardio aspect between each obstacle. The default cardio aspect is a .10 mile run but gyms can opt for a machine/ exercise alternative.
​
After each event, participant's time/ score is place into a standings. Their placements in each event are averaged for an overall score. Each participant's score goes to their gym's overall score and their individual score for the Championships held in late April/ early May.
