It is not uncommon for riders to play favorites when it comes to which indoor cycling classes they will take. As instructors, we see our regulars every week. They often go out of their way to tell us how good of a job we are doing and how much they loved the whooping we just planted on them. The indoor cycling world spins happily on its axis week to week, and all is well until…we need to find someone to substitute our class. Chaos. Struggle. Picketing. Riots. Panic.
