Today's run was amazing. I ran 3 miles on my "easy trail" (just 200 feet drop and climb in 1.5 miles). Then I added in a more vertical road loop that climes 200 feet in a half mile to see how I would do breathing. I entered into the climb and while my breathing deepened it was still slow(er than it used to be) and relaxed. I could feel I was really raising the CO2 in my blood supply and also reaching my threshold at which I could maintain my pace.
On a second run, I did one of my favorite trails, a 4 mile out and back, with a 900 foot climb in the first mile. I definitely pushed my limit the whole way up, but literally within steps of the trail getting less steep I was already able to have a short pause in my breathing.
It is truly amazing to be running in "primal glide" while breathing slow with a pause. No billowing cloud of breath in my visual way in the 5F air. No cold mouth or lips. Just properly warmed air by the time it got to my lungs. This sure feels like how we're born to run!
Plus 8.5 miles
Total: 427.3 Miles
