I’m new to the forum, and am rereading both « Training for… » books (a lot to grasp when new to all of this).
As many, and assuming I have ADS, I started my training with long runs and hikes at my MAF-calculated AeT of 125 bpm.
But I would like to do a real AeT test and not rely on the « 180 – age » formula.
I don’t have access to a treadmill and don’t have a fancy GPS / HR watch to record things for Training Peaks.
What I do have, is a small Garmin hiking GPS (that’ll record speed and distance at intervals), a basic HRM (with chest strap), that displays real time Heart Rate (but doesn’t record it over time), and a nice horizontal running area that goes for miles (along a canal).
The GPS isn’t precise enough in the speed measurement for me to use it to pace myself and run at a constant speed, but what I find pretty easy is to regulate my effort when running so that I’m within 2 or 3 BPMs of a given heart rate.
With this, is it possible to do a kind of « reverse treadmill heart rate drift test » (where I’m keeping heart rate constant and varying speed) by running 1 hour at a constant heart rate, and divide distances covered during the first and second half hours ?
If, say, I cover 3 km the first half hour and 2,85 km the second, is my heart rate drift 3 / 2,85 = 1,053 = 5 % ?
Thanks for your help !
I just did this. I tried my best to keep my heart rate stable. According to my wahoo every mile I ran i had an average heart rate of 145 or 146, max 151 for the entire hour, so within 5%. My mileage for the 1st 30min was 2.32miles and the second half 2.28miles which is 1.8%, so do that mean I need to increase my heart rate and redo the test? Or is 145 my AeT?
