Short for training time today? Try high intensity overgeared intervals.
Overgear training will uprecruit muscle fibres and train fibres normally only used at the end of a long training day. The athlete who can resist the most fatigue will win the most races. If you can’t train long, you need to train smart.
What do to? Use the AIRhub to reduce your road speed and aim to hold a cadence of 60rpm. Ride at maximum effort for 3 minutes, followed by 3 minutes easy, repeat. This type of ride is perfect for short commutes or pre-dinner training sessions around your suburb.
