Your VO2 max is a measure of the maximum amount of oxygen your body can utilise during exercise. If you increase your VO2 max, any run below that level is therefore easier (in theory). Spending time training at VO2 Max intensity will generate performance enhancements for runners of all distances but runners and triathlete running distances up to 10km will benefit the most.

Testing yourself with max efforts is a great way to develop your speed with an appropriate training stimulus. This is a great session for triathletes and open water swimmers to do to build their speed.

Spending time training at appropriate intensities is important for developing your ability to ride at different paces or intensities in an event. For a half-Ironman event you will spend most of the event riding at Level III (about 77-90% Functional Threshold Power). This session is great for a taper week leading into an event. Even though this workout is designed for a half-Ironman athlete road cyclists especially those doing a century and mountain bikers can also benefit from it.
