Haven't posted here for a while but for those who check you know I've taken up MAF training. Well it's been about 20 months of it and I hit a milestone: Total nose breathing!
I had noticed on one of my runs last week as well as some bike riding that I wasn't mouth breathing as often as I used to. In fact, my breathing wasn't as labored (relatively speaking) as I had been accustomed to. So today I decided I would only run as fast as I could while only breathing through my nose.
6.5 miles later a finished run without even a gasp. And it wasn't a slow one. Not race pace but not slow.
