Unbreakable Runner


Unleash the Power of Strength & Conditioning for a Lifetime of Running Strong

By Brian MacKenzie, T.J. Murphy

Unbreakable Runner challenges conventional training tenets such as high mileage and high-carb diets to show how reduced mileage and high-intensity training can make runners stronger, more durable athletes and prepare them for races of any distance.

Distance runners who want to invigorate their training, solve injuries, or break through a performance plateau can gain power and resilience from MacKenzie’s effective blend of run training and whole-body strength and conditioning.

CrossFitters who want to conquer a marathon, half-marathon, or ultramarathon will find endurance training instruction with 8- to 12-week programs that combine CrossFit™ workouts with run-specific sessions.

Unbreakable Runner includes CrossFit-based training programs for race distances from 5K to ultramarathon for beginner, intermediate, and advanced runners. Build a better running body with this CrossFit Endurance-based approach to running training.
