@lumpy19doing a PR mile towards the end of a run, and because I was trying to burn off some calories quickly before bed, i did a shorter run last night with a fast (for me) mile in the middle. Usually if I try to do a fast mile I warm up a little and then try to lower my heart rate before starting, but starting with a jog and then going faster felt pretty good. When I have done intervals I usually try to go faster and/or for less than a mile. And when I try to run this pace I can sometimes go further but usually bonk after some distance. So this was nice. I might make this my new model for treadmill running, start with a slow mile and then do longer and longer distances at my goal pace.
Googled a little this morning and found this

I average about 6mph regardless outside so I'm probably on the faster side of jogging than actually running. And seeing some of the points they make about decelerating when your foot lands in front of you and how that can lead not only to wasted energy but injuries makes a lot of sense. So now I'm hoping to get out there today for a longer run and try to put some of this stuff to work. Even if it means I'm actually slower at first as I'm getting used to it, or tire myself out and have to walk for a while, it's probably better long term if I put this stuff in practice outside and not on a treadmill, and on some of the longer flat areas later in my run than the hilly bits closer to my house.
I know I've heard good runners talk about heel strike and I'm not totally sure what that means. I have tried the bouncing on your toes running before and my feet hurt for days afterwards from using totally different muscles and probably incorrectly.
Any thoughts? I just don't want to do anything stupid and hurt myself.
