What is the primary reason a RiderCoach may counsel out riders?

Answer: C — For being a risk to themselves or others

Counseling out riders is a serious decision that must not be taken lightly. It is essential for the safety of both the rider and their fellow riders. A RiderCoach may counsel out a rider who is posing a risk to themselves or others due to reckless behavior, lack of focus, or not following safety instructions. This decision is not based on the rider's speed or difficulty in the course, but solely on the potential danger they may cause. Therefore, options A, B, and D are incorrect as they are not valid reasons for counseling out a rider.
