Crossfit Endurance: Brian Mackenzie

In this episode I talk with Brian Mackenzie, Crossfit Endurance coach and author of Power Speed ENDURANCE: A skill based approach to endurance training . Crossfit Endurance features a lower volume, high intensity approach to training for endurance events. This way of training may help you stay injury free while achieving the same results and in less time than traditional approaches to endurance training. Brian has completed 100 mile ultra-running events while never running more than a half marathon in training.
