Does this sound familiar? You ride comfortably and can chat easily – and yet you get faster over time? That is exactly what is behind the current hype around zone 2 training. Even world-class riders like Tadej Pogačar swear by it. Sounds too good to be true? It isn't. Here comes the simple explanation.
Does this sound familiar? You ride comfortably and can chat easily – and yet you get faster over time? That is exactly what is behind the current hype around zone 2 training. Even world-class riders like Tadej Pogačar swear by it. Sounds too good to be true? It isn't. Here comes the simple explanation.
What is zone 2 anyway?
Zone 2 is a training range with moderate intensity – usually between 60 and 70 % of your maximum heart rate.
Simply put: you ride so easily that you could still chat without any problem. It feels almost too slow – and that is exactly the trick.
What happens in your body?
This is where it gets interesting. Three important things happen in zone 2 at the same time:
- Your body burns fat in preference to carbohydrates – fat burning is trained.
- Lactate levels stay low – your body learns to work efficiently with oxygen.
- Your aerobic base is built – the foundation that makes all intense sessions possible in the first place.
Think of your body like a car: zone 2 is driving in the most efficient rev range – not too fast, not too slow. Over time nothing wears out, and the tank (your energy reserves) lasts forever.
Why is zone 2 so important?
Most amateur cyclists make a fundamental mistake: they ride too fast almost all the time. The result: the body never truly trains fat metabolism, base endurance stays weak – and the foundation is missing for more intense sessions.
The recommendation is clear: about 80 % of training should take place in the easy zone 2 range. Only 10–20 % belongs in the high-intensity zones.
Zone 2 training sustainably improves:
- base endurance
- fat burning as an energy source
- the efficiency of the cardiovascular system
- your ability to get through long rides without hitting the wall
And the best part: it barely feels strenuous, hardly burdens recovery – and you can do it almost every day.
How do I find my zone 2?
You don't need complicated performance diagnostics for this. Two simple methods:
Method 1 – the conversation rule (simplest): ride so that you can talk fluently. If you can only get out single words, you are too fast. If you could sing, you are too slow.
Method 2 – the heart-rate rule: calculate 60–70 % of your maximum heart rate. If you do not know your exact max. HR, start with the rule of thumb "220 minus your age" – even if it is somewhat inaccurate, it is perfectly adequate for getting started.
Zone 2 in practice: what a typical session looks like
| When | What | Duration |
|---|---|---|
| During the week | Easy ride in zone 2 | 60–90 min |
| Weekend | Long ride in zone 2 | 2–4 hours |
| After hard sessions | Active recovery in zone 2 | 45–60 min |
Important: the heart-rate monitor or power meter is only a helper – your feeling is what counts. If you are struggling too much, you are no longer in zone 2.
Conclusion: sometimes less is more
Zone 2 training is the opposite of the "always full gas" mindset. It requires patience and a rethink – and rewards you with a stable base, better fat burning and more endurance. And once you have a solid zone 2 base, you benefit doubly from intense sessions later.
So: next time you get on the bike – dare to ride slower. Your body will thank you.
