If you aren’t taking data points about yourself then how do you know if you’re making progress? Recording the variables can allow you better training protocols as well: are you recovering well enough? Did you bite off more than you can chew in the beginning of the workout, only to burn out and try to survive until the end? What if you just slowed down and paced it out more intelligently? Writing notes down like that can definitely help you out the next time some similar flavor comes around.
