I recognize this from my running days, even so long ago.It's called, getting your legs in shape. My lungs still take time to "open up" by even that is faster. But the heavy tight leg feel that I used to have so often is now noticeable absent or diminished.
Heavy day yesterday too and usually that really slows me down but not today. Takes forever to get in decent shape but it's so cool when you're finally there. Or at least close enough to feel it

pack weight goes up 2 lbs next week. lets see how that goes. Nice crisp morning out and that always helps. The heat adaptation is kicking in much more slowly this year. One thing at a time I guess.
