No, TrainerRoad currently does not have a "multi-rider", or fitness studio licensing available.
We do offer Group Workouts, but each user must have their own active TrainerRoad account to participate. It is TrainerRoad's policy that each rider has their own account and that more than one athlete can not use the same TR subscription.
If you have any questions about multiple rider use with TrainerRoad, please email our Support Team at support@trainerroad.com.
