Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

There are many definitions for "threshold" in addition to methods used to find your training zones. One method that I've heard works well is to do a 20 minute time trial with a hard sprint at the end. Your average HR over the last 15 minutes is supposed to be a good indicator of your threshold HR. The max that you hit in the sprint is a good indicator of Max HR.

What I'm unclear about is what this HR is supposed to represent exactly - HR at FTP (functional threshold power), MLSS, lactate threshold, or something else.

It doesn't really mean anything.

Use it for training, not for quantifying your abilities.

Lactate threshold is a power, VO2, or intensity. It is not a heart rate. However it is defined, LT can be determined only by drawing blood and measuring lactate concentration.

Intervals should be above LTHR. Search for "intervals" in the forums... then do some every week.

How you train is complicated. Go buy carmicheal's book or Friel's book.

But very simply, if you are working on your base (aerobic) system, you stay underneath it a fair bit, if you are working to improve your ability to deal with lactic acid, you ride near it, and if you're working on anaerobic power, you work out as hard as you can.

But how you mix them depends on your goals and how you're training.
