FTP using HR zone as indication

[novetan]

I started to understand a little about FTP and its usefulness. But I’m not a serious cyclist and don’t intend to install one of those power meters. I also do aware an alternative measurement is to use heart rate beat, although its never as accurate. It is also reactive instead of proactive, meaning lag time and not instant feedback. In the absence of a power meter, I cannot complaint about its drawback and I reckon at least it will give me some indication.

May I ask the expert here if I were to base my FTP using HR Zone (which contains 5 zones), to what zone shall I ride for sustainability?

If I understood any of that I would answer, but I don't, so I won't

My understanding of FTP is based on sending files from one computer to another, but I don't think you mean that.

I'd suggest googling Friel or Carmichael and FTP test. If you want some ideas around this send me a personal message.
