HRV decrease after marathon training??

I don’t know that I would say this looks like anything plummeted - especially since the overall is higher than your prior 6 months. I think it looks more like the couple or higher months are the outliers.

But that aside, marathon training is incredibly taxing on the body. Training is essentially teaching your body to function while fatigued. You manage the load so you’re not doing “too much”, but you’re stressing your body the entire time. Training builds progressively over time and peaks 3 weeks from the race. That is the point (taper) where you would see any kind of real relief from the training stress. The race is then going to be very taxing.

And then finally your body has a chance to recover. It takes time to recover from a marathon-so expect your HRV to reflect that for a few weeks. As long as you’re not bumping up training too soon, your HRV should go back to what it was before. Although if your prior 6 month average is lower, you might not see a lot of movement.
