I have been dealing with small injuries here and there over the last couple of years. I recently had a consistent block of training from March to the beginning of August, and my AeT started at 140 and moved up to 152 over the course of this training (using a chest strap and a very well-controlled HR Drift Test on a perfectly flat course). Then life happened, I got busy and also did the big no-no: really long efforts on the weekends, resulting in me being too tired to train consistently during the week for about the last 3 weeks.

I plan on doing a spot-check for my AeT next week, but I’m curious to hear the experience of others with regard to how much AeT can drop during a period of inconsistent or no training. Hopefully that will give me an idea of where to aim for the test. Thanks in advance!
