That’s a hell of a post Steve, and has to be the be the clearest concise summary of the different thresholds and HR zones I’ve seen. I’ll be saving that for reference 🙂

As sad as it is, I’ve come to the conclusion my test was completely useless for as measuring my AeT.

I’ve just ran a HR drift test targeting 155bpm (workout in Training Peaks: http://tpks.ws/FCJ5WJS677LBNTI4FEYTRMETSU), that being about where I expected to find my AeT going into the test. This came out with Pa:Hr of 2.73%, suggesting 160pbm as a more realistic AeT HR.

The AnT number from my test seems almost dead on where I’d have expected based on past workouts at 178 (I’d have guessed 180), so I’ll roll with that number for the time being at least. That still keeps me just outside the 10% difference between AeT and AnT, so I’m still just about in the realms of ADS.

Bottom line after all this is that I wasn’t far off before and just confused myself by getting a test which didn’t quite achieve what I wanted, even if it did shine a spotlight on my poor fat utilisation. On the up side, this has made me spend some more time thinking critically about what I’m doing, which is never a bad thing!

Apparently that photo was too large. Here’s my test results.

Thanks all. There’s been some interesting discussion of the definition of AeT which has given me some stuff to process.

I’ve attached my test results, for those of you who asked.

Going back over the results myself. I’m starting to suspect the test started out too fast. I plan to do a drift test later today to attempt to sanity check the results and will report back after that.

Thanks Rachel, those threads are really useful and give me quite a bit to digest.

I’ll put off the Z3 work until I’ve improved my fat utilisation.

137bpm is pretty awkward in that I struggle to get my HR up above about 110 walking on the terrain I have easily accessible midweek, but can’t keep it bellow about 145 running even slowly. Perhaps I’ll have a play with adding weight to walks and see how that goes.

From the threads you linked and the article posted by Dada, it’s probably also worth experimenting a bit with my diet.

I suspect the advice from here, will be to do most of your aerobic runs at intensities up to the crossover hr?

So this is the bit that has me unsure. Despite the seemingly high AeT HR, I don’t have a crossover point. Even at rest I was only getting 35% fat utilisation.
