The why
Endurance is mostly repetition. We think that's the good part.
Same pool. Same loop. Same hill, four more times. Nobody posts about rep six of ten, but that's where the PR gets built. pace+interval is for the people who keep coming back to it, and quietly enjoy the joke.
Too much noise
Gear covered in slogans that shout louder than your coach.
Too little humor
Endurance is absurd. Somebody should admit it.
Too much motivation
You don't need a poster. You need the next interval.
Do it for the PR
