Product DescriptionThe key to faster time trialing is improving your ability to sustain higher levels of output (power) over a longer duration. By boosting your anaerobic threshold, you'll become more efficient and be able to generate more watts for a longer period of time before fatigue sets in, allowing you to ride faster in the 'race of truth'. In this workout, Spinervals 32.0 - EXTREME Threshold Training, Coach Troy guides you through an effective, challenging (and sometimes painful!) series of threshold sets designed to stress your anaerobic energy system and 'raise the ceiling' of your AT.
