Ultra-Endurance Training

Ultra-Endurance cycling events are typically defined as a race that is over 100-miles. These events can take place on a variety of surfaces and with any sort of bike, but their duration brings into focus the importance of your nutrition, hydration and pacing strategies.  

These types of events cover a wide range of durations. 6-7 hour events represent the lower end of the range, while 24-hour events and multiple day events represent the long end. Regardless of the duration, ultra-endurance events will follow a similar recommended training approach due to the similar energy system demands over those durations.

As an ultra-endurance racer, aerobic endurance needs to be a primary focus. During the race, it is crucial to limit your exertion to your Endurance Power Zone to help preserve your energy for the long event ahead.
