Training, by the evidence.
Long reads that take a real training question back to the research: what the studies actually found, how strong the evidence is, and what it means for your riding.
What does Zone 2 actually do, and who is it for?
The Rise and Reassessment of Zone 2
Where the 80/20 idea came from, how one cross-sectional study became a longevity prescription, what 353 studies say about mitochondria, and where the hype outruns the evidence.
Where is my Zone 2, and how do I find it without a lab?
How Do You Actually Find Your Zone 2?
Why 220 minus age and fixed percentages miss it for so many riders, how the talk test, HRV and drift tests compare, and a step test you can do on your smart trainer.
How much hard training should sit alongside the easy riding?
How Many Hard Sessions a Week?
Two a week is the accepted wisdom. We tested it against elite training data, frequency trials and recovery physiology, and found when one or three is the better answer.
Put it into practice
The training planner turns this research into a week: two hard sessions, easy riding that grows with your hours, and an optional long ride.
The research says: keep easy riding easy.
