Hi Holly,
I’m interested to know how you got on with this. Did you find a HR for 5% drift in the end?
I’m also a 46 yo runner and about to try my first AeT HR drift test and not sure what HR to target. I recently ran my first road marathon (downhill for 40 mins, then very flat) at 165bpm average and with 1.3% drift. Just looking at the flat section where my pace was very stable, PA:HR was -0.2% over 2hr50.Seems like AeT must be higher than 165…
