Apologies – I’m new around here! But I’m still appreciative of all of y’all helping point a total rookie in the right direction!

I just got my chest strap HR monitor and will report back with the results.

Looking at the HR graph on Garmin Connect, looks like my HR was a more reasonable (although still lower than I expected) BPM. (min of 110 bpm and max of 140 bpm).

Like you mentioned though, around the 10 minute mark, my HR just drops (even though I’m definitely more gassed). This could also be correlated with me dialing the speed way back, but I do wonder if what happened to you is also what happened to me.

Either way – looking forward to getting some better training data when my chest strap monitor comes in!

Definitely agree the chest strap will help – but I don’t think the inaccuracy of a wrist HR monitor explains a 60+ bpm discrepancy… unless it does.

Just from everything I’ve read online, the accuracy of the wrist HR monitor can be about 7% or so. But I could definitely be wrong here.

That totally makes sense!

It’s just strange, as Training Peaks recommends to set the grade at 15% (steep) and keep it there.

Overall (even with my normal aerobic base training), I usually have better luck getting my HR closer to AeT on flatter/milder terrain – there comes a point in steepness where I noticed my heart rate actually chills out but my legs start to give out. So I’m guessing what’s happening there is a similar phenomenon as what I saw at my attempt at the Anaerobic Threshold Test.

On a side note – reading some of the pinned posts revealed to me that I need to get a HR chest strap! I don’t think using a wrist HR monitor completely explains what happened with my Anaerobic Threshold Test, but more accurate date can never hurt.
