Hey Joe! Any thoughts on doing a 30 minute test at the end of a fast-finish long run??

I'm not too concerned with tracking pace (output) yet as much as simply determining LTHR (input) at this point in my training (base phase). Or, does it not really even matter I know LTHR yet as I'm sticking to pure aerobic training ... although how do I know what is optimal aerobic if I don't know the zone thus needing LTHR?

Have you ever prescribed aerobic training NOT using your 30min LTHR test? (Similar to MAF-type calculations) ... then get the LTHR when we're ready to enter build phase (out of base)??

(I've been out of training for ~18 months and want that aerobic engine back, although I'm feeling great after ~2.5 months at ~7hrs/week running w/ 20mi long runs feeling great by the end)

AdamC--The only problem with doing an LTHR test at the end of a longish run is if you are tired. That may well mess up the results. And you're right: You should know LTHR in order to estimate aero\bic thold. Formulas don't really work. They assume that everyone's HR at a given age is the same. Is no more true than everyone's shoe size is the same at a given weight.

Joe, just for right understanding, you wrote" "That's an approximation of your LTHR (also often referred to as anaerobic threshold or functional threshold heart rate)."

You mean: AT is the same that LTHR/FTHR is?!

I read your books, and I learnt this is not the same...

Joe Friel

Bartosz--They're "approximately" the same. All occur at about 7 RPE of 0-10 scale.

Hi Joe,

I'm new into running and read about determining the LTHR. I've done the test accordingly (30minutes with max effort). However, the LTHR I get is 193bpm which is I think is really high. I'm 25 years old.
Hope to hear your opinion.

Joe Friel

Radhiozil--While it may be higher than what is average that doesn't mean it's wrong. You're simply on the right side of the bell curve. Some people have big feet and some people have high heart rates.
