80/20 Endurance

Train slower.
Race faster.

Based on the best-selling books, 80/20 Endurance plans are built on the intensity balance elite endurance athletes actually train with: mostly easy, so the hard work counts. And now every Team 80/20 membership includes Mind of Matt — an AI coach trained on Matt Fitzgerald’s complete body of work, reading your real training data. Not a chatbot with a sports vocabulary. The world’s foremost endurance coach who has seen your week.

Over 250,000 plans sold

The method

80% easy. 20% hard. All of it on purpose.

Most self-coached athletes train too hard on easy days and carry that fatigue into the days that matter. Decades of research on how elite endurance athletes actually distribute their training keeps landing on the same answer: about 80 percent low intensity, 20 percent high. Matt Fitzgerald codified it in 80/20 Running and 80/20 Triathlon. Our plans put it on your calendar — over 250,000 of them sold and counting.

Athletes on the method

Don’t take our word for it

Over 250,000 80/20 plans have been sold, from first 5K to hundred-miler — and the method’s case was made in print before we ever sold one: 80/20 Running and 80/20 Triathlon are where thousands of athletes first learned to slow down.

  • I PB'd every race I did this year and then topped it off with my first 70.3 thanks to the 80/20 plan I used! PB'd the Olympic distance at nationals! The 80/20 method really changed my approach to training and got me fitter than I've ever been without a single injury.
