I know it's a rhetorical question, but why on earth do other peoples' workouts bother you so much? If you have such a better training plan than they do, then you obviously will vanquish them in competition, thus validating your own personal worth, I suppose.
1) Sunday long run. Unless you do marathons and ultras, you don't need so many longruns. Let alone every week on the most cliche long run day of the week. Sheep.
2) 1km repeats. Wow, aren't you special using the metric system even though you're an American. I bet you call soccer "football" and refuse to drink cappuccinos after 10am too. Cringe
3) 20 minute temple run. Again, too cliche, usually done too fast and too seldom.
What workouts do you consider the most cringe?
