A bit of both.
For sleep, I have focused on improving sleep habits. Going to be earlier but at similar times including on the weekend. I noticed a negative impact staying up later on Friday and Saturdays even if I tried to sleep on a little longer. I started using earplugs and at times a sleep mask. The mask is very helpful on days when the sun comes up and I’m still sleeping as our blinds don’t completely block out light.
I’ve used the Recovery score to tweak training and have chosen to back off on certain days, especially when I wasn’t recovered well and knew I had other hard days coming up. This helped bump my recovery score and then went hard at it in the days that followed.
It’s going to be very interesting using Whoop in the two weeks before Leadville. I’m going to be moving from low to high altitude a couple weeks before the race and prior experience has shown this will impact my HRV. I’ll also be managing training and tapering at this time. The altitude and dry can also make it harder to sleep.
