Comments: I believe I did this with murph. Cadence indicates I was not running. I remember a Green Mountain hike where I decided to relax on the downhill, and this was probably it.
This effort has me thinking HR training stress could be improved. It seems to work OK when I am running (consistent high intensity), but it misses the mark when it comes to low intensity stuff. I'm considering switching from IF = HRavg/HRthresh to IF = (HRavg - HRrest)/(HRthresh - HRrest). Just looking for a good metric when pace isn't applicable or available.
