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.

“CrossFit Endurance founder Brian MacKenzie and Ironman triathlete T.J. Murphy shoot down distance-running doctrines in Unbreakable Runner, and explain how upping intensity, slashing mileage, and incorporating specific strength and conditioning work will make you a stronger, faster, more injury-resistant runner — whether in a 10K or an ultramarathon.” — Men’s Journal

“In his new book Unbreakable Runner, MacKenzie tears down these traditions to reveal the new rules for fast, powerful running.” — Competitor magazine

“MacKenzie has opened doors to coaches and runners, offering proven solutions to a myriad of problems that persistently vex runners of all ages, abilities, and backgrounds.” — Dean Karnazes, ultrarunner

Unbreakable Runner should appeal to all those with an injury-prone background who want to seek a more effective ways of training.” — Athletics Weekly

Unbreakable Runner is a game changer. For 10+ years I followed a “traditional” approach to training for races from 1/2 marathon to 100-mile distances with mixed race-day results. After turning 40 and recovering from knee surgery, I made the decision to change things up and fully embrace the programming laid out in Unbreakable Runner. I’m now not only a stronger, faster and more resilient all-around mountain-athlete, I’ve set PRs across the board and achieved race-day results I never thought possible.” — Bob Africa

Unbreakable Runner is a must-read for anyone interested in improving performance, maintaining a balanced and healthy body and achieving longevity in the field of athletics. The plans and principles described in Brian’s book have allowed me to reduce my average weekly mileage by over 60% while still routinely breaking 24 hours in some of the most challenging 100-mile races around. More importantly, this foundation has created the opportunity to replace the junk miles with training that has produced a stronger, healthier, more balanced and overall productive person. I finished Western States in 23 hours on 21 miles a week following this plan. The training isn’t easy but the plan is crystal clear.” — Steve Crane
