Cutting-edge research has proven that triathletes and other endurance athletes experience their greatest performance when they do 80 percent of their training at low intensity and the remaining 20 percent at moderate to high intensity. But the vast majority of recreational triathletes are caught in the so-called "moderate-intensity rut," spending almost half of their time training too hard--harder than the pros. Training harder isn't smarter; it actually results in low-grade chronic fatigue that prevents recreational athletes from getting the best results. In 80/20 Triathlon, Matt Fitzgerald and David Warden lay out the real-world and scientific evidence, offering concrete tips and strategies, along with complete training plans for every distance--Sprint, Olympic, Half-Ironman, and Ironman--to help athletes implement the 80/20 rule of intensity balance. Benefits include reduced fatigue and injury risk, improved fitness, increased motivation, and better race results. Review: Solid science and writing - As someone who studied exercise signs in school, I’m usually pretty skeptic about books on anything health and fitness. however, Fitzgerald outdid himself here with this book applying well-known scientific principles to triathlon and is making it easy for the reader of any level to understand his thinking and apply the learned material. Review: Incredible Book to Unlock Huge Gains! - Thank you Matt Fitzgerald for a very easy to comprehend approach to making huge gains with the 80/20 approach. Like many, I would do training runs for years in the threshold zones and hit brick walls on performance improvements. I have been following his Level 1 Half Ironman training workout and have been making huge gains. For example, my LTP 5 months ago was 7:17 minutes per mile. After performing the same 30 minute running test on the same course and in the same conditions, my LTP is 6:45 minutes per mile. Another factor is that I am following the diet guidance from his Racing Weight book. No need for a personal coach if you follow the training plans from both of these books! In fact, I believe his expertise is far superior to 95% of the coaches out there. Be sure you create a journal to log your workouts also as this will help you understand small refinements you may need to make. Matt Fitzgerald is the man! ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #86,561 in Books ( See Top 100 in Books ) #7 in Triathlons (Books) #11 in Track & Field Sports #98 in Running & Jogging (Books) | | Customer Reviews | 4.6 out of 5 stars 934 Reviews | ## Images ![80/20 Triathlon: Discover the Breakthrough Elite-Training Formula for Ultimate Fitness and Performance at All Levels - Image 1](https://m.media-amazon.com/images/I/91BIjQj2+6L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solid science and writing *by M***R on December 11, 2025* As someone who studied exercise signs in school, I’m usually pretty skeptic about books on anything health and fitness. however, Fitzgerald outdid himself here with this book applying well-known scientific principles to triathlon and is making it easy for the reader of any level to understand his thinking and apply the learned material. ### ⭐⭐⭐⭐⭐ Incredible Book to Unlock Huge Gains! *by A***R on April 9, 2023* Thank you Matt Fitzgerald for a very easy to comprehend approach to making huge gains with the 80/20 approach.

I completed my first full distance triathlon using the Be Iron Fit book/plan and it went very well. Always tweaking, I wanted to see what this book had to offer in planning for my 2019 season. I really love the concept of training easy the majority of the time (hence 80%) and then including very specific intensity for a specific purpose. The book includes the science behind the idea, which I appreciate, but also the practicalities of how you figure out your training zones in each discipline (swim/bike/run). There is also good strength training advice in here. I am definitely planning to use one of these plans for my upcoming half race in May and I am excited to see the results! ## Frequently Bought Together - 80/20 Triathlon: Discover the Breakthrough Elite-Training Formula for Ultimate Fitness and Performance at All Levels - The Triathlete's Training Bible: The World's Most Comprehensive Training Guide, 5th Edition - Strength Training for Triathletes: The Complete Program to Build Triathlon Power, Speed, and Muscular Endurance --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/76145741-80-20-triathlon-discover-the-breakthrough-elite-training-formula-ultimate](https://www.desertcart.co.uk/products/76145741-80-20-triathlon-discover-the-breakthrough-elite-training-formula-ultimate) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-26*
