Making an endurance training program can be difficult for most runners. Sticking to a training plan can be even harder. Below we outline an easy method to determine if you are training as effectively as possible.
The 80:20 Method of Maximising Endurance
The 80:20 method is a basic principle of endurance training. When followed correctly, the 80:20 method will maximise your endurance gains and reduce the risk of overtraining!
Simply, 80% of your running volume should be in Zone 1 (low intensity) whilst 20% should be in zone 2 & 3 (high intensity) combined. The table below outlines the basics.
Research suggests that in moderately trained individuals, high intensity interval training will improve VO2 Max values significantly more than doing the same volume of running at sub-maximal intensities (Helgerud et al., 2007).
Long slow runs. These are the mainstay of any endurance athletes training program. They are the long days out, best run at “conversational pace“. In combination with high intensity training, long slow runs have a significant role in improving performance markers such as running economy. They also improve your bodies ability to tolerate the load of running long distances.
These are your “Threshold runs”. This is a much smaller proportion of your overall training volume. Threshold runs are run at a “comfortably hard” pace, usually similar to an athletes 10km race pace, or 15s/km faster for well-trained athletes.
High intensity training. This type of training involves intervals of all out bouts of high intensity running, with rest breaks between each interval.
Improving VO2 Max is only one aspect of endurance training, it is not the be all and end all. However, increasing VO2 Max will make easy runs naturally faster, as your perceived effort at a certain speed will reduce.
