Mostly easy, sometimes hard

The 80/20 idea

Roughly four rides in five are easy and the rest are properly hard. Skipping the middle, the "kind of hard" pace most of us ride by default, is what lets you recover between hard days and still improve.

What is FTP?

Functional Threshold Power is the power you could hold for about an hour. Every target in a workout is a percentage of it, so the same plan fits a beginner and a seasoned rider. Take the in-game FTP test, or the plan's final ride, to set yours.

What each ride is for

The strip on each card is the actual workout, warm-up to cool-down.

The eight weeks

Hard days never land back to back. Week 4 eases off; week 8 tapers.
