Watts are the rate in which you produce energy. On your bike, you produce higher watts the harder gear you are in, and the higher your RPMs (revolutions per minute - a.k.a the faster you spin your pedals).
The Tour de White Rock - Pro Ride class has a focus on high performance cycling by training with watts, RPMs and/or heart rate as your guideline for each drill.
Use this class to help push your endurance levels.
Train the athlete within to achieve your personal or team best.
