PM - treadmill tempo 1 mile warm up then 6 miles at tempo with a 1 mile cool down. Did not feel that great. Thought about pulling the plug on it about halfway - but pushed through. My training practice, perhaps a little old school (seeing as I am kinda old) has almost always been to grind through planned workouts even when they are not going particularly well - and I know there is a school of thought to do the opposite - but how do you know when. And, if you push through tough workouts when you don't feel that well, won't that experience assist you later in races when things get tough?
