Peter Attia adjusted his running goal to 5:06-minute miles due to training plateaus.

“I never could do the five 5-minute miles I don't know what it was like I could do so I really I changed that to five six-minute miles which I could do again not just to move the goal line but because I also realized like I was just not gonna get to five five so you could have that goal on there forever but at the time I certainly didn't know how to train for that I'm not sure I ever could have but the way I was training which was in retrospect running far too long and far too slow was gonna plateau me there”
