Is Zwift worth the monthly subscription for indoor training?

Zwift costs $15-25 per month and provides virtual worlds, structured workouts, group rides, and races. If you train indoors more than twice a week during winter, the motivation and structure justify the cost. Free alternatives like TrainerRoad offer structured workouts without the virtual world if you prefer data-driven training.

Do I need a fan for indoor trainer riding?

Yes — a fan is the single most important indoor training accessory. Without wind cooling, core temperature spikes rapidly, power output drops 10-20%, and sweat production overwhelms. Use a high-velocity floor fan aimed at your torso and face. Two fans are better than one for serious sessions.
